How Is this Wrong?
URGENT

Vertex form in general is y = a(x-h)^2 + k

The vertex is (h,k) = (-1,-5)

So

y = a(x-h)^2 + k

y = a(x-(-1))^2 + (-5)

y = a(x+1)^2 - 5

Now plug in the given point (x,y) = (2,13) to isolate 'a'

y = a(x+1)^2 - 5

13 = a(2+1)^2 - 5

13 = a(3)^2 - 5

13 = 9a - 5

9a - 5 = 13

9a = 13+5

9a = 18

a = 18/9

a = 2

The equation goes from y = a(x+1)^2 - 5 to y = 2(x+1)^2 - 5
