[rANdomiZER5273]

What about 1/4x^2?

i love you

Thx for helping me understand how to find the vertex! really helps!!! But ny teacher says that he wants us to make a table, and find other points on the parabola; on the graph, do u know how to find other points on the parabola? lmk, thanks! :)

@adw1997packers sorry, i meant "My teacher, not "ny" teacher.

OMG THANK YOU D:!

but how would you find the vertex of y = (x + 4)(x - 2)

i cant find any youtube videos that have this function :/

[DariusIsBomb]

@ImTheAwesomeGirl1 i think you have to either foil (x+4)(x-2) or make them equal zero so x+4=o and x+2=0

you are a god.

i need help it says "find the vertex form of f(x)=2x^2+24x+62"

[mroldridge]

@rc843 1. Find the vertex, according to this method.

2. Write out this: y = ___ ( x ___ )^2 + _____

3. In the first blank, write whatever you have in front of x^2 (for you, it's "2")

4. In the second blank, write the x-coordinate of the vertex, but flip the sign

5. In the third blank, write the y-coordinate of the vertex, and keep the sign the same

THANKS! BECAUSE OF THIS LESSON, I GOT 100% ON FINAL TEST

[GoProKing1682]

i actually think your a god right now. you saved my ass for my test tomorrow! Great video!

[jsscgarcia835]

Thank you so much I FINALLY understand it is so easy now thank you

[greglalatv]

if we had negative x square (-X2) wud the vertex still be (0, -3) ?

[greglalatv]

thanx alot :D

[Caglosemo]

perfect, thamks a lot =D
