y =  \frac{1}{3}  {x}^{2}  - 3

Step-by-step explanation:

The general vertex form of the equation is

y = a {(x - h)}^{2}  + k

where (h, k) are the coordinates of the vertex and a is a constant. In your case, the vertex is located at (0, -3) so your equation becomes

y = a {x}^{2}  - 3

To find a, substitute the point (3, 0) into the equation

0 = a(3)^2 - 3 ---> a = 1/3

Therefore, the equation has the form

y =  \frac{1}{3}  {x}^{2}  - 3
