You can put this solution on YOUR website!
The equation is in standard form and you can read the point for vertex and axis of symmetry. The graph is a parabola opening downward and has vertex at a maximum.

y=-3%28x%2B2%29%5E2%2B4
A parabola with equation in standard form y=a%28x-h%29%5E2%2Bk has vertex (h,k) and axis of symmetry is x=h.

y-intercept? Let x=0 and solve for y.
