Determining the quadratic equation given a vertex and a point
👉 Learn how to write the equation of a parabola given three points. The equation of a parabola is of the form f(x) = ax^2 + bx + c, where a, b and c are constants. Since, the equation of a parabola has 3 constants, three equations and hence three points are needed to solve/obtain the equation of a parabola.
Given three points on a parabola, we use the standard form of a quadratic equation to set up a system of three linear equations which we solve to obtain: a, b, and c and hence, the equation of the parabola.

You know that liberating feeling when you finally understand something because someone can actually explain it to you in a way that makes sense...that's the feeling I'm getting right now! Thanks for this video!!!

It's 11 at night and my assignment is due at 11:59, I couldn't understand this at all, and i then found this video and I was 5 seconds away from turning off my phone and just putting in random numbers and I'm genuinely grateful for this video.❤
It may have been 8 years since this video was posted, but I want you to know this video is still amazing!

literally watching this in the middle of a test. online classes suck but that's one perk of them. Thanks man, super helpful.
It's crazy just how easy and straightforward you can make it. I have had teachers who have taught the generation before me and you are still able to explain it 100x better than them. Thank you!
good teacher.

GODDD why aren't you my math teacher. I already know most of this stuff because I do an extracurricular math program so I'm way ahead of my class but sometimes I need refresher and this was so perfect my math teacher barely explains it and I can barely remember what I did since it happened so long ago in the math program. I can't imagine what it's like for the kids who haven't seen this stuff yet. thanks anyway man

Just a correction, f(x)=ax2+bx+c is standard form and f(x)=a(x-h)^2+k is vertex form. Not the other way around. Otherwise, very helpful. :)

thank you for posting these examples. don't know if you're still monitoring this, but did you mix up the form names when you said them at :16? Isn't f(x)=x2+bx+c standard? and f(x)=a(x-h)2+k vertex?
