This video explains how to determine a quadratic function given the x and y intercepts of the graph.

This video has literally changed my life and has given me a sliver of hope in passing my PreCalc class. Thank you.

This video helped me so much. I was struggling on my precalc homework and you helped me understand this. Thank you so much!

I swear I learn more from him than ANYONE! he is never boring and his voice makes me calm..

[GamerofWorldWars]

Really helped out my memory lapse on the subject, thanks for the good explanation to jog my memory!

how do I get the equation if I only have 2 x intercepts

[wannabememelord]

saved my butt on a test today, thanks man!

[topatosalt]

im 9 years late but thanks, this is te only video that i found explaining it. :))

[gabi]

thank you so much, i think I'll pass my algebra 2 midterms because of you!

This video was posted on my 7th bday. Happy birthday to me!!!🥳🎉🎉🎉

Thank you so much! In my book they gave some crazy method that wasn’t making sense. Now I get it! I just have to use intercept form. I was trying to use standard form and I wasn’t getting it

[Realcernunnos]

thank you for making this concept extremely easy, I may yet pass Precalculus

[KimberLeighWheaton]

Thank you. I was at my wits end until I found your video!

What do you do if you are not given a y-intercept?

[Ofaseer]

What if you're y intercept is (1, 6) instead of (0, 6) would you put f(1) instead of f(0)?

[natelamb]

Oh I tryed for hours then I watched this video and it was easy thanks

[miradelalune]

thank you for this video! It really helped me out :))

can we write r1 = -4 and r2 = 3 instead of x and x?

[chrispyyycream]

what if you dont know the x axis of the max value?

[QuubsaaNuuraa]

sketch the graph of the following 3x²_5x+7

[verysmartscholar]

wait i thought f(x) was like y, and you couldn't substitute x because it was y, if that makes sense? I dont know and this is due
