- 👉 Learn how to graph quadratics in standard form. A quadratic equation is an equation whose highest exponent in the variable(s) is 2. To graph a quadratic equation, we make use of a table of values and the fact that the graph of a quadratic is a parabola which has an axis of symmetry, to plot some points to one side of the axis of symmetry and then refrect the plotted points about the axis of symmetry.

8 Transformations You MUST KNOW to graph a quadratic - ua-cam.com/video/HgWs_yDkjps/v-deo.html
The guy who asked *where did u get 2a*
Is literally me in maths class
lol I was too, you really have to learn how to enjoy lectures so you don't get distracted easily
@@countdracula2836 It's not bad to ask for questions. Why would they be called "teachers" if they don't help the students learn. We go to school to learn anyway, not to judge.
but where did he get it tho
@@aerickajm9298 It's an equation you use. You plug in "a", in this case it would be 1. Use the first equation on the top of the board for reference.
@@siuol_ly6141 when i ask questions they be like "oh im not going over it again i already taught u how to do it"
It's so sad watching how little your students appreciate you. If you were my math teacher, I'd leave my phone at home when I came to your class. They have no idea how lucky they are to have a teacher who actually knows how to teach
amen to that...
Sad to see how little you appreciate your education. This teacher is like any other ive had i dont know about you so stop bitching about how bad you have it and leave your phone at home with the teacher you have now.
@@mr.thundercock4961 Some teachers quite literally don’t want to do their job. My math teacher for the past two years would shove us in one of the classrooms in the school library and just leave us without giving work (so she could go drink coffee with her teacher friends). When we would go to ask her what we are meant to do or to ask for help because no one knew what we were doing she would tell us that we need to problem solve and ask our peers or just straight up ignore us. Then when 75% of the class failed she would lecture us on effective studying and how we were “slacking off”. So you see, I would be thoroughly grateful to have a teacher who actually taught.
@@arialoe4210 I wouldn't waste your time, they are probably a troll. Their name is "Mr Thundercock", sooo probably best to ignore.
True man
Just have to remember this for 10 more years, then it’s paying my taxes for the next fifty
Facts
you still remember?
8 now

8 more to ago
Why did I learn more here than I did in a week of my math class
Lmao update I failed my test because I ran out of time
Ha
Oh no
@@rynnieTS we have been on this chapter for more than a month and we are barely taking the test tomorrow and I forgot everything
This is faster paced for more advanced learners
Because this teacher knows his stuff
I only wish my math teacher in class would explain like you do. Your video helped me understand this problem ten times better. Thank you sir !
you are very welcome!!!
@@brianmclogan yeah thank you so much!!
OK bye
Yeah this is a good teacher

MetaDragon and then you fall asleep and then wake up on 3:40 and give up and do it in school 😭😭😭😭😭I’m a high school freshman and I may die someday
Rahaf Satary HS freshman you say, well goodluck.
Bro use photo math it’s free
ranveergames lol thats a bad idea, when you cheat you dont understand anything for the final, if you dont understand the final you fail
Archinoc I understand everything I just use it to save time
When you are in 11th grade but you forget 8/9th grade material so you have to come back...
Thanks for the video anyways.
I forget cause my teachers dont explain anything
Literally me rn
@@Jennifer-lw1kk I might be switching to a better school cause of this
Relatable 🤧
when you are 36 and flushed ALLL of this 20 years agoooooo
Everyone is talking about how they learned this in 10 minutes but took them 2 weeks to learn in school, but nobody realizes that this is a school lesson.
The difference is they were self-motivated this time.
they can pause the video and rewind
@@pamelastoesz733 The difference is the teacher knows how to teach.
yes well it's not a school lesson from MY school, which sucks by the way
@@michellewest6929 Exactly
0:31 find axis of symmetry by using the formula (. x = - b/2a )
2:18 but first determine if graph is going to open "up" or open " down"
when a>0 ( a is greater than 0 ) your graph is going to open "up"
*MEANING the vertex is going to be a "minimum" point .
3:13 NOW WE'LL FIND our tables of value AFTER determining if our graph will open "up" or "down" .( ask , how is our "x" value of our vertex related to our axis of symmetry ? 3:57 )
our vertex HAS TO RUN THROUGH our axis of symmetry , and since we determined **by using the formula ** ( x = - b / 2a ) that our "axis of symmetry" is 4 , THEN our x value of our vertex IS ALSO 4 .
4:17 how to determine y value ( really your * f(x) value ** ) of the vertex by plugging your x value of your vertex in your function ) so you can "graph " the vertex .
5:13 determine atleast "two points " to the left and "two points to the right of your "graphed vertex ) by table of values
6:36 using shortcut of "symmetry " by finding two points to the left or right and "since" its symmetrical you can jus "mirror your three "graphed" points you have , to finish graphing ...
tysm!!!
thank you so much! would you mind explaining why we say f(x) instead of y?
yeetus deletus ik I’m late but the reason is because in a quadratic equation it’s a function so it’s f(x) but it’s basically the same as y, it’s just used to easily input values
THANK YOU SO MUCH THIS HELPED ME
I LOVE YOU SO MUCH
Who else has been watching math videos all morning because of a test or exam

When you accidentally add this to your playlist and in the middle of Taylor Swift you get quadratics...
sounds like a fire playlist to me
u get the aux

I been struggling with this for awhile and my teacher could never explain it the right way and he teaches too fast. Now i finally understand.
I been struggling too, its been a year now you so you probably got it by now. tryna help me out?😏

u roasted a student how do you feel
It was funny
lol that aint right
Awesome Duh

No school's ever right. Kids who fight back will end up in the office for assault or something like it. Counselors aren't helpful either. My suicidal friend got better because of his parents, not the counselor. Don't even get me started on the nurse and teachers
KingCP08 :D lmao that’s so true, the nurse would be like “Got asthma? Here’s an ice pack”
1:35 I can relate.
Lol same u got ig maybe we can talk be friends lol idk

😐
Lmao nigga got curved

Your students are very lucky. Our notes when we went over this didn’t even have the vertex formula on them the teacher just kinda mentioned it once and expected everyone to memorize it. I could probably dig up the notes and take a picture for proof.
UA-cam videos in class are always better than the actual class. 😂
The Teacher: As you see in your notes
Me: What notes I'm not in your class
Why did i learn this in secs but in school i was saying huh the whole time
Facts.
Because your weren’t paying attention lol
@Lauren Idc That’s mostly the case.
Thank you so much! My math teacher is great, but he tends to overcomplicate things sometimes. This really helped clear it up. Wish me luck for the test tomorrow!
Did you pass?
@@v7ll588 This was two years ago, but yes, I did pass. Good luck on your exams!
For nearly a week now I’ve been completely out of sync with my advanced algebra 1 class, but you managed to catch me right up to speed and in such a short time. Thank you so much for what you do
I really appreciate your videos because I have a hard time understanding my math teacher. Which caused me to feel stuck and struggled to understand the material. I love how you mention so much information in just a very short video. You are a life saver! Thank you!
bruh you just taught me this in 7 minutes and I actually got it while my teacher takes like 5 days to teach this and I have no idea what she said
Why cant school teachers actually teach like this.
It looks like some guy just recorded an algebra class.
that's exactly what happened tho
dude you are a legend teacher, you explain things so simply! I love it, I am gonna hit that like button!!!
The world needs more proactive teachers like you. Thank you!
rn I’m in quarantine and I have to get packets for my school and I missed out on a week of work so I’m getting confused with these numbers. You’re always the one I go to for these types of things, ty for helping me!
Hey Mr. McLogan, I know this video is ten years old but I just gotta thank you for making content like this. I don’t always understand math because my teacher isn’t very ensnaring and has no energy, but I really got the hang of it. Thanks
you are a million times better than my math teacher. i would literally fly to where you teach and just have you lecture me for a few minutes daily. i understood it better than i ever did and i thank you for that.
“Where’d you get 2a” we literally had the same question
Absolutely legendary math teacher, why are you not teaching in a university? You’re so much better than any math professor I’ve had
you have professors explain quadratic graphs to you...?
@@meloviiii huh?
Lol, I'm gonna be coming here a lot cause I dont understand anything, I know how to complete the square, solve by quadratic formula and factor but I dont know how to graph it :(
I'm gonna fail the test like always, I honestly have like 3 hours before an exam
same though, my test is tomorrow uggh
Lmao the person at the end who sarcastically said “great!”.
I have watched around 10 videos yet not understand the concept and watching your video made everything clear ten times better. Thank you!
This helped me a lot.. such a nice explanation!!
I have an exam on quadratic functions and you helped a lot thank you!
Thank you for these explainations so clear and easy to understand, straight to point without unecessary things.
Real they always dragging out the lesson
this video was a life saver because were learning quadratics in algebra and were having a test on quadratics today, and I was still a bit confused. this taught me literally everything i needed
I wish your students had payed more attention. This is SUPER HELPFUL! I had just learned this today and I payed attention, and I forgot. This explains this a lot better that how I learned them. Thank you!
Why are UA-cam videos so much more helpful than real class

I have to say the way you teach is quick and precise, super easy to understand. Your students are very lucky to have you as a their math teacher.
I'm taking a BSEd course major in mathematics, but we gained little knowledge during online class and this video helped me to go through the lessons I don't understand. Thank you so much!
I just wanna say thank you so much for this video ! It is almost EOC testing time next week and I need some help. Thank you so much for guiding me through this math work with graphing quadratics !
Might be a old video but it helps a lot !!
I have my math 1 EOC today 🥲
Couldn't u also just complete the square to find the vertex and then factor to find x intercepts?
Your channel is sick btw!
Precisely. He made up a table instead using the function of y.
This may be an older video but it was a huge help! I’m a freshman in college and embarrassingly needed googles help with this again - but you’re the first person who’s explained it in a way that made the concept stick!
I wish I had a teacher like you...so calm and friendly, sadly your students appreciate it a little
Wow that was simple. Thank you so much.
My eighth grade teacher isn’t too helpful in explaining this yet. I appreciate all the help
Neither is my 11th grade teacher. It's one thing to give out answers and another to help you understand. Good luck!
Mr. Mclogan, I just wanted to say thank you! Your videos have been of great help to my son. Keep the good work 👏🏼
Wow. My book and teacher made this way more challenging than was needed... Thanks for this.
Thank you so much, my math teacher does not explain at all, you saved my math grade!!
Thank you bro that helped I wish I could be ur student
I am doing FLVS and literally made so much more sense. Thanks you so much Sir!
Sir, Your explanation was flawless. My teachers have always explained it in some other obnoxious way that I never understood. Your short clip just saved me so much headache. Thank you so much. I really appreciate your efforts.
Thank you so much! Im behind in my class due to medical reasons and this made things so much easier for someone who struggles in math!
Lelolichan u good?
I hope you are doing well
I hope all is well!
Oh man. I was doing my algebra 2 homework and its the same exact question which helped me understand the rest of it. Thank you so much
SkateGod 2.o wtf you mean Algebra two? We’re doing this in my Algebra 1 class rn.

Mr. Mclogan thank you so much you made me ace my test I’m a freshman in TN and you’ve been helping me for my studying
This channel always helps me so much, always happens to pop up whenever I need help with math and never fails to catch me up!
Finally understood this lesson, my teacher is giving us a hard time understanding it. Thank you very much
We personalise teaching on the premise that every human being is uniquely made/created. Every students has intelligence that is unique and different from other students. Similarly learning abilities and styles also vary from student to student. Keeping in view this theory one on one class with student can help student more in learning than a combined class.Moreover, it would be easy for a teacher to assess student by pointing out weakness and work on them to enhance learning and performing best in the exams etc. This can only be made possible if a teacher is certified pedagogist and he/she excelled in subject/course teaching content with enough teaching experience. We offer following course individual tutorial/classes online.
Mathematics: Grade 1-12 (IGCSE/A,O levels), Canada, USA, UK based syllabus
Physics Grade 1-12 (IGCSE A/O levels), Canada, USA, UK based syllabus.
English grammar and composition.
Biology upto grade 8.

Thank you sir. You made my life a lot easier, at least until we move on to the next lesson. Lol
this SAVED ME. I've been staring at the same page for a week now before I found this, and now I finally understand!!
This guy explained it in the best way than all other videos I watched. My appreciation and respect!
Very helpful, thank you!!

Bruh, the interruptions make these videos so much better lol.
Thank you so much! I am taking precalc summer school and this was a helpful review. I am into skipping math classes and sometimes I miss a bit on subjects so thank you for the quick review.
This really helps me
My algebra 1 eoc is tomorrow and my teacher sucks I’m legit going to fail she never even taught us to do these steps in this order thank you so much 🙏
Thanks for the help ❤️
My mocks tomorrow 😊
Thank you! Your lectures have been helping me more now that we're in pandemic and i got no choice to learn but self study since online class doesn't really help with my unstable network.^^💜
its 4th quarter and this is the only thing getting me through this chapter
Very nice
. Thanks
you are very welcome Sayan!
Thank you so much Mr McLogan, this helped me a lot :)
Mr. Brian, you have NO IDEA how much this helped me in plotting my graph. Thank you SO MUCH!
Thank you very much for explaining this subject more clear!
I hate to say this but if a student asks "how did you get 2a" the answer was "Because that's the formula for... That was in your last class notes", is a terrible response... Obviously the student didn't get the importance of that formula and it should've been reiterated... This is definitely why I never got math either... teachers who dismiss a student's honest question with a shitty attitude. #BadFormSir
I feel like he would have explained it if he wasn't in the middle of making a video. Who knows, maybe he explained after the video was done.
Right, I’m studying for a quiz tomorrow and I want to know where he got 2a from!
Rolanday same I idk I am in 5th grade
its a formula, you cant explain a formula, you just explain how to use it
There is no explanation for a formula...him saying that its the formula is the best he can say and he would obviously become frustrated if it had been explained previously and no attention was paid to it
THANK YOU SO MUCH, Was having sm trouble and coulsnt get any of my work done but now I understand it completly. Tysm I wish you well.
THANK YOU THANK YOU I had absolutely no clue what my teacher was saying today and you really simplified it for me.
If this video or many others was helpful, please consider letting me know with a "Super Thanks" above ⬆. I am able to read and respond to all my messages and thank you so much for your support
Super thanks
Super thanks sir

Just saved my exam grade thanks so much
Super mega thanks
Im so sad im in the edge of failing gr9 because of math :(
You are making it a lot more easier to understand, thank you.
