Answer:

Step-by-step explanation:
Hello, please consider the following.
When the parabola equation is like

The vertex is the point (h,k) and the focus is the point (h, k+1/(4a))
As the vertex is (3,-2) we can say that h = 3 and k = -2.
We need to find a.
The focus is (3,2) so we can say.

So an equation for the parabola is.

Hope this helps.
