The equation is in vertex form y=a%28x-h%29%5E2%2Bk where (h,k) is the vertex.
(h,k)=(-2,-8)
The vertex lies on the line of symmetry, x=-2
If the parabola opens upwards, the vertex y coordinate is the minimum y value.
If the parabola opens downwards, the vertex y coordinate is the maximum y value.
In this case, ymax=-8
