Question

Suppose a parabola has a vertex (-8,-7) and also passes through the point (-7,-4). write the equation of the parabola in vertex form.

Answer 1

\(y+7=3(x+8)^2\)

Answer 2

The answer is y=3(x+8) -7 .. I just dont know how to get it

Answer 3

Vertex form is: \[a(x-h)^{2}+k\]

Answer 4

\[(h,k) \] is your vertex

Answer 5

I know that but when I plug the problem into it I don't get the correct answer. What am I doing wrong. Can you please explain how to do it to me

Answer 6

So -8 and -7 are vertex

Answer 7

-8 = h
-7= k

Answer 8

a ( -7+8) Squared + 7 is that right

Answer 9

Subtract -7 from both sides of my equation.

Answer 10

No.
