y=+-x%5E2-3

the vertex form of a quadratic equation is

y=a%28x-h%29%5E2%2Bk+....where h and k are coordinates of vertex

If a%3C0+, the parabola opens downward. In this case the vertex is the maximum, or highest point, of the parabola.
you have
y=+-1%2A%28x-0%29%5E2-3=>the parabola opens downward, h=0 and k=-3=> vertex is at (0, -3)
