Question

What is the equation of the axis of symmetry of the quadratic equation y = 2(x – 4)2 + 7?

Answer 1

Do you mean\[y=2(x-4)^{2}+7\]

Answer 2

\(\large\text{if you help me with this, I will love you forever.}\)

And yes.

Answer 3

Ok

Answer 4

So you know that vertex form is \[y=a(x-h)^{2}+k\] and that (h,k) is the same as (x,y) right?

Answer 5

Yes.

Answer 6

Well the axis of symmetry is just x. And since x is 4 in this, the equation of the axis of symmetry is x=4

Answer 7

Do you understand?

Answer 8

Kinda. The part I don't get is the (x-h)^2 part. I forgot the rule for squaring things inside of parentheses ._.

Answer 9

oh wait. I feel kinda dumb now.

Answer 10

don't even need that. Sorry for being a dingus.

Answer 11

o.O

Answer 12

So do you understand?
