Find the equation of the parabola, if: the focus is at (0,-3) and the vertex is at (0,0)

Explanation

To find the equation of the parabola with the given focus and vertex, we can follow these steps:

### Step 1: Identify the Vertex and Focus
The vertex is given as \( (0, 0) \) and the focus is at \( (0, -3) \).

### Step 2: Determine the Orientation of the Parabola
Since the vertex is at \( (0, 0) \) and the focus is below the vertex at \( (0, -3) \), the parabola opens downwards.
