SOLUTION: Write the equation of a parabola with vertex (-3, 5) passing through (-4, 6). Find the values of x when y=8. i have NO idea where to even begin.

Hi,

Using the vertex form of a parabola,  where(h,k) is the vertex

vertex (-3, 5)

y = a(x+3)^2 + 5

parabola passes through (-4, 6)

6 = a(-4+3)^2 + 5



6 = a + 5

1 = a

Equation of parabola:

y = 1*(x+3)^2 + 5  Or y =(x+3)^2 + 5
