I prefer the equation for vertex form as follows:

where (h,k) is the vertex.

The vertex is (7,8)

The axis of symmetry is the line x=7 as it's a vertical line running through the vertex.

X intercepts are when Y=0, but with the vertex above the X axis, and the parabola opening up, there is no X intercept.
