Since the vertex is at and (which means that when , then ), this means that the vertex is at the point (0,8). Now remember, the quadratic has the vertex (h,k). So this means that in this case and

Start with the general quadratic in vertex form

Plug in and

Subtract

So the quadratic equation which has the vertex at (0,8) is where "a" can be any number. For example, has the vertex at (0,8)
