Is this function inverse, sir? f^-1(x)=3√x? Thanks again sir
I have a question. Is the second example an Inverse function? Shouldn't it be one to one function only?
@@ifgosdjjhgjiuzahgiuwgr4137 sometimes when you inverse a function, the inversed graph is no longer a function, take y=x^2 for example
can you teach my algebra teacher how to teach please
Same heree oof
SAME😔😔😔😔
That's basically why I'm here.
Same right here😓😓
Lol same prob with my teacher
you just explained in 2 minutes what my math teacher failed to in 2 hours.. thank you
What is your grade?High school or elementary?
@@user-xj7ms2hy7l You're right thanks for showing me how to be mature. I'll go try starting an argument on youtube later
Math class for two hours damn
same, i feel u
My G💪💪Have understood something that I had failed to understand in a whole semester
after watching this video, my skin is clear, life is good, and I'm feeling blessed.
Lol i can relate...
your skin clear now huh
I can see your skelaton
No cap
@@marcomartinez89stress gives you acne, in case you missed the go comment’s point.
Yes the videos from 2006 are helping
I know right ! Lol. And it's all free
❤️
i can literally memorise the ad better than the formulas i have to memorise
Lol I fucking hate that ad
lmaoooo u right
His voice is soooooooo soothing and calm. He knows when and how to speak, to clearly get his points across! I wish he was my Precalculus tutor! I wish I knew his name! Thanks man!
literally having my Finals math test in about 30mins, you just explained this quite easily and i actually understood it quickly.
Good luck ! I hope it’s going well
How did you do
Yeah but how did you do
i have my exam in two days....idk i dont have an ad math background and just started some revision lol, this vid helped alot ! how did u do btw?
THEN WHY AM I REWATCHING THIS 10 TIMES AND STILL DONT UNDERSTAND WHAT KIND OF BRAIN DO I HAVE 😭😭😭🙄
The side effects of having a bad math teacher: watching math videos on youtube
Khai Vo doing it the night before a test lol teacher doesn’t teach shit
@@noluck4678 omg mood. I have a test tomorrow and I'm watching this before I sleep and try answering similar questions tomorrow
@@yumitsoo
I hate when they don't tell you to round or not so you get points off or the entire question wrong, I hate my life my stupid brain
No
@@yumitsoo no
In 11 minutes, you just explained what i've struggled the whole morning to understand. Keep up the great work! :)
Bro, you are a blessing in this world, can't express how much we love you. Long live Organic Chemistry Tutor
he died?
@@kingdunlap1908 no lmfao
Struggled with these kinds of equations for 2 years, 2 YEARS. Thanks for making this explanation easy to follow and nicely placed out. 👍
Same.
Feeling when u get to college and gotta take a precalc review and u don’t remember shit
I didn't even need to watch the whole video, within the first minute exactly at 1:04 it all clicked and I understood something that 3 different teachers in real life couldn't properly teach me. Thanks a lot.
this guy is the best, period.
The dude teaches like my former math teacher, who made me feel like a math genius with his teaching method.
Lmao your yt name correlates to your comment
there is just a thing with your voice. It sounds so refreshing and chill. Makes me acc like math. You explained everything so well
I’m in pre calc and myself and a lot of other people in my class are struggling to understand this. My teacher teaches so fast and doesn’t really bother to make sure everyone actually understands what he’s trying to teach. This video was a godsend. Thank you.
I've been watching your videos for the past two years. The reinforcement to topics I learned over twenty years ago are well explained. This has served as a great opportunity to retain important math concepts that never go obsolete.
same ive been watching his videos for 3 years now and he always has something new
Amazing how proper instruction can actually help one understand the subject matter.
You don't use big words at random times and do it all in chronological order which makes it so much easier for me to understand😊
Fam you telling me your teacher doesn’t give it to you in chronological order
@@truthdetective4925 Nah, he skipping all over the place, placing the domain after he has already done the whole equation
You’re an angel!!! I’m trying to revisit all the material I learnt back in high school and your videos are such a blessing.❤️
I truly thank you from my heart for all of your hard work and everything you do to help us. Thank you ! ❤️
So all of us here have bad math teacher huh
No we don't all have a bad Math teacher. Mine js great! I just can't be bothered to search through the long recordings of the lecture and go through people asking questions throughout. That takes too much time
I love your easy style and managed to follow you easily even though i've never done this before, thank you
I wish you were my school teacher. My school teacher is always complex in explaining and make me feel like an idiot. You just made mathematics look simple to me I feel like a smart kid .
literally struggling to answer a question and this video immediately helped me understand. thank you my guy!
Sir you are a life saver. Thank you from the bottom of my heart, many might not see this. But teachers like these save the lives of students.
The way you taught this concept it was so clear! For the first time in my life i understood maths so easily! Thankyou so much!
you sir are definitely gifted. the ease with which you explain topics like this is just mind blowing. thank you so much
2:36 Was able to do my math problem after this point, That's all you had to say, and it helped me immensely, thank you.
Dude you have never failed me! From high school and now college
you are a god sent man thank you! I just started my first year of biomedical science but I need to catch up on some of the maths and your videos makes me not want to throw myself off a building!
dude thank you so much, you explained in 11 minutes what I had been confused about for a week. you're a lifesaver
My teacher is so bad that I swear the first minute of this video helped me more than a 20 minute video from him
So helpful in a time when I can’t even see my algebra teacher
this is so easy, I wasn't expecting it to be this simple. Simple math like this makes me feel a little smarter.
thank you so much. I can't express how much your lesson meant to me. the way you taught... excellent
best in the whole world. thx for explanation
Thanks so much for this, you are a good maths teacher.
Thank you for being a wonderful substitute/teacher when needing help. I am not strong in the arithmetic area.
bro explained my topic that i've been working on for 5 DAYS of wracking my brains out in 1 minute and 14 seconds. life is good mate
Thank you so much, since we have converted to digital learning and we haven’t started using zoom yet for online classes because of the pandemic you are my go to source for all of my questions and they are always answered.
You make it so easy. Thanks!
MR. Organic Chemistry Tutor, thank you once again for another smooth explanation on How to Find the Inverse of a Function.
this is very helpful. Easy to get, easy to understand thank you!
DANG IT! I was watching then Karlie Kloss came on saying how to make a website with wix! Appart from that, great vid!!!
Wtf r u watching this
Ratio
Ohh ur here
A minute in and i already understand better than what my algebra teacher “tried” to teach us
I have a test on this tomorrow and I didn't understand it until now. Thank you so much! You are such a great teacher!
in 11 minutes you explained what my math teacher couldn't. this is very helpful, thank you!
yall know when the math final GRIND comes around, this guy is my lord jesus christ
omg thank you for all of the great examples and not just leaving us with one trash problem while walking away with the middle finger and saying good luck 😭
Serious time
My teacher, doesn’t properly teach.
Spends a day per topic.
Test on as soon as we’re done with a chapter.
Assumes we’re all understanding.
Hmm, it’s a fast class. And I just can’t keep up.
Your videos have helped me a lot!
I had DAYS trying to understand this, the first 2 minutes were enough to understand this!! thank you sm
wow very interesting, i am gonna good at mathematics, thank you sir, even i don't see your face,
i have CAT, this next week, promise you success, cause it's been long days without understand this
Thank you so much for this video! I genuinely had so many difficulties understanding this for literally months since it was first introduced in my school and tutoring place. All my friends seem to already understand this concept and I felt really left behind and shameful that I didn't quite understand this concept yet. I didn't expect watching an 11 minute explanation video on youtube would give me my sudden eureka moment, but I absolutely did and it felt otherwordly. It just goes to show that you don't really need to spend a ton of money on tutoring to be able to understand and learn things. It's currently 11PM and I have a math test tomorrow so watching this is really helpful. I will be forever in your debt.
I have seen so many videos of inverse functions but I understood yours the best thank you.
i appreciate this guy so much he explains so well and i understand everything so quickly
was about to kms, this vid helped☺️
The amount of trig teachers who dont know how to teach and the people here are both amazing and sad as hell.
Man you have a talent of teaching , i have learnt four chapters by your help . Award of best teacher goes to you
thank you very much for your utmost dedication to the explanation of thim amthematrical concepts you are a blessing indeed
thank you so much
1:44 Finally.... softh!
Thank God for this guy. The textbook my school prescribed for us I couldn't understand it. This guy made me understand this. Thank you
I swear to god you are a miracle it literlly took me 2 hours on your channel to understand everything I have been trying to understand the past year THANK YOU SOOOOO MUCH like really dude your videous should hit 30 million subscribes it's more usefull than story telling or funny videous
Is there a order to how you arrange after cross multiplying? Cuz i just crossed multiplied, got the exact same answer but with inverted symbols. (Last problem)
same here, idk what it is
nvm, its nothing to worry about because both functions are the same.
Do u have a video of graphing inverse function?
Plug in random x values once you solve it and graph it like you would graph a regular function.
BLESS UR SOUL this concept had me in a chokehold up until now
Not me struggling to remember how to solve for inverse for almost a year and this guy removing my doubts in a matter of minutes
After the military I decided I wanted to go to college. I'm in my late 20s in remedial math. I thought I was going to major in CS. Although I have an A in my last remedial class, I think I'm too dumb to continue in CS. I'll be switching my major to something in the humanities. Sometimes my math homework makes me want to cry. I'm done trying to force something that I'm just not very good at. I'm always the top student in my liberal arts classes. I guess I'll stick to what I'm just naturally good at.
Alex Ledesma wishing you luck. I sympathize with your struggle in math. I find math beautiful and fascinating but cannot manage to be good at it.
what's CS
Explosive Elephant It stands for computer science.
@@icesnowflake5510 ah thank you
Explosive Elephant Np!
Ah yes the organic chemistry is strong in this one
Usually I wouldn't be watching these videos since I understand in class, but online classes are burning me out, which made me go here. My previous year's math teacher attaches your videos for us to learn our lessons in advanced. This year, my current teacher only just does lectures and sends us PowerPoint copies of the lectures (not saying that it's wrong, because that's my current teacher's teaching style).
Like I said earlier, I usually understand the lessons once discussed, but online class burn out didn't make me listen to class at all, or motivated or keep me focused. And that burn out brought me back here.
I would like to sat the videos may be simple, but I find it entertaining with how simple it is.
Anyways, I better stop typing this comment before I distract myself from this lesson since my homework for this is due for today!
thank you so much! I'm preparing for finals and this is very helpful, easy to get.
TLDR: just swap the x and y. Y = 3x + 4 becomes x = 3y + 4 just get the single Y by itself and you are done.
How do you inverse with fractions?
AniJam you reverse the numerator and the denominator and if there is like subtraction or addition you just do the opposite of what it is. So if it was like y= 3/5x + 7 it would be y= 5/3x - 7
Caution510 _ thanks
Thank you this video was so clear and it explained so many different example of inverses so it’s so very helpful
It’s amazing how this guy could teach me this in 1 min and 11 sec.
May you pls help me with this
f(x)= 3x-3
4
how do you get rid of a cubed root?
DomoKilla cube it
cube both sides of the equation.
Cube both sides like she said
I have an exam the morning I'm watching this😢
how was yur xm??
i just became a tutor for college algebra, but since i haven't took the course in six months-- i needed to remember everything so thank you so much!
You make every topic so much less frustrating. Ty!
i will pass precalc. say it with me. Love you, Muah 💋
my question is :
x ≥ __
easy to follow nd easy to understand. well appreciated, much love
We gettin outta pre calc with this one 😤 thank you so much bruh
Who else is here in 2020 during online school because teachers cant teach worth a crap
lol, same, i feel dumb when im the only one who doesn't understand in my class
Jillian_star my teacher just sucks 😂
@@Icy_815 samme,
i mean, how did our teachers even get a teaching degree?
Jillian_star I’ll ask a question and he’ll pause and then keep teaching
there is literally no point in switching the x with y
You made me understand this thing in 45 seconds.
Thank you so much!
Literally thank you so much, I understood in 5 min, and my teacher couldn’t explain in it in a whole hour, thankss
THANK YOU!!! This video came in clutch.
Struggling with this equation just a week ago,tysm,u just explain it to me in just 2 min. that my teacher have failed to explain it to me lol ,keep it up
After 5 years this video still helping, thank you so much!!!
Thank you! If I could give this video a 1000 like I would. You are a blessing!!!
My Pre-cal professor can’t explain it like you do.
Have a precalc test tomorrow and this is SO HELPFUL.
Damn bro, now my life is blessed and I'm feeling overwhelmed
well... im studying for finals and your 99% of my review and refresh on stuff i already learned (also u) ur the goat
Good teacher! semple and clear demo. Thanks
thanks a lot, the factor thing is what i forgot i feel uplifted !!!
this is the only channel i will watch the ads for cause he deserves it
you're videos are sooo useful every single time
This man saved my life. My math teacher is fine, but his english is absolutely horrible and i couldnt understand anything, now i did tysm and kudos to you
