Thank you so much! This was a whole lot better than how my teacher was teaching. He does it so fast, it's hard to keep up. When you teach it, you show the process thoroughly.
Thank you so much! I was extremely confused before this video and this is one of the topics that I really needed help with. Like the way you explained and it labeled the steps and answered the possible questions that I and others would've asked. Cheers!
If the b is odd, then your axis of symmetry will be a fraction. For example, in x^2 + 3x + 2, -b/2a would be -3/2. So your axis of symmetry would be x = -3/2. You won’t have to do any steps differently in the problem, though I agree fractions do make some of the math more awkward. Hope that helps! 🙂
I think there may be an x missing after the 9. If so, you can absolutely solve this problem using the steps in this video 😊. Here’s a quick summary: First graph the parabola. To do that, I recommend you use x = - b / 2a to find the axis of symmetry, where 9 is your b and 1 is your a. Once you have x, plug it into the equation to find the y and you have your vertex. Plug in a couple of values to the left and right of x to get some points to graph. Then look at the greater than/less than sign in the original equation to determine whether the parabola should be a solid or dashed line. Finally, pick a test point to determine where to shade. (For this kind of problem, I would definitely recommend watching the video since there’s a lot of graphing and visual parts to it 🙂- I just don’t feel like I’m explaining it as well in this limited space 😓)
Yes 🙂. We always want to shade the area that makes the statement true. If the test point you pick makes the statement true, shade where that test point is. If it makes the statement false, shade where that test point isn’t.
I slept through the whole wekk of class. I have an exam in 30 min. Thanks so much
Glad I could help! 😄
@@YouCanLearnMathwithAlyssa just finished it. Was incredibly easy. I used your method and I believe I aced it
@@Freedom-denier That's awesome! 🥳
@@Freedom-denier how did you do?
@@4kil_4had1 year later but i aced the test

Aw thank you so much! I’m so glad to hear it helped 😊
Never did quadratics but needed a lesson to help a friends kid for a test. You made it so simple.
Thank you so much for the kind words - hearing these videos are helping makes my day! 😊
My weak concepts grewed and became stronger thank mam❤
Omg i was struggling all week with this stuff and you make it sooo simplee thanksss
Aw thank you so much for the kind words - I’m so glad I was able to help! 😊
This was a brilliant explanation. Thanks a TON.
Love from India.
Thank you so much - I’m so glad it helped! 😊 India is such a beautiful country - I really hope I get to visit it someday!
Thank you. Keep up the good work. Very straight forward and efficient explanations. Earned a subscription from me today.
Thank you so much! 😊. If there’s any specific math topic you’d like me to cover, please let me know
This helped me study further into my lessons! I think im advanced studying...❤
So glad it helped 😊! Best wishes with your studies 🙂
Thanks so much, I understood this topic very well now ❤
great video. simple and clear
Aw thank you so much! 😊
this was so perfect explained. i understand it, thank you!
Thanks so much for the kind words - it makes me feel so great to know I could help! 😊
So clear thank you...former math teacher helping son..superb instruction
Thank you so much for the kind words - so glad I could help! 😊
What is the b is odd number?
If the b is odd, then your axis of symmetry will be a fraction. For example, in x^2 + 3x + 2, -b/2a would be -3/2. So your axis of symmetry would be x = -3/2. You won’t have to do any steps differently in the problem, though I agree fractions do make some of the math more awkward. Hope that helps! 🙂
Thank you soo much 😄. This just saved my grade and my semester 🙌 😌
You’re welcome - so glad to hear it helped! 😄
Thank you! You explained this perfectly. I finally understand!
Aw so glad I could help! 😊
You are amazing!!! Thank you soo much!!!

are you sure about the shaded region
Yes 🙂. We always want to shade the area that makes the statement true. If the test point you pick makes the statement true, shade where that test point is. If it makes the statement false, shade where that test point isn’t.
This helped so much thank you
You’re welcome - I’m so happy it helped! 😊
Thank you!!
You’re very welcome - so glad it helped! 😊
Love the gifs!
tyy soo muchh teacher now I think I have a chance to finish my tomorrow"s exam
So glad it helped - best wishes on your exam! 😄
@@YouCanLearnMathwithAlyssa thank you mrs alyssa
Thank you so much
You’re very welcome! 😊. If there’s a math topic you need help with that I don’t have a video for yet, please let me know!
you talk too much about nothing to do with math
Hahahaha 😂
I think you're just dumb
Too much nonsense talk get to the point
