Write an equation of a parabola with the given vertex and focus.

Vertex: (-3, -4)

Focus: (-3, -3)

The equation of a parabola can be represented as:

(x - h)^2 = 4p(y - k)

Where (h, k) is the vertex and p is the distance from the vertex to the focus.

Given the vertex (-3, -4) and the focus (-3, -3), we can see that p = 1.

Therefore, we can substitute the values into the equation:

(x + 3)^2 = 4(1)(y + 4)

Simplifying gives us:

(x + 3)^2 = 4(y + 4)

This is the equation of the parabola with the given vertex and focus.
