Find the equation of the parabola that satisfies the given conditions:Focus `(0, 3)`; directrix `y = 3`

Explanation

To find the equation of the parabola with a focus at (0, -3) and a directrix given by the line y = 3, we can follow these steps:

### Step 1: Identify the focus and directrix
The focus is at the point (0, -3), and the directrix is the line y = 3.

### Step 2: Determine the orientation of the parabola
Since the focus is below the directrix (focus at y = -3 and directrix at y = 3), the parabola opens downwards. Therefore, the equation of the parabola will be in the form:
\[ x^2 = -4ay \]
