Find the equation of a parabola whose vertex is `(-2,0)` and focus is `(0,0)`.

Explanation

To find the equation of a parabola with vertex \((-2, 0)\) and focus \((0, 0)\), we can follow these steps:

### Step 1: Identify the Vertex and Focus
The vertex of the parabola is given as \((-2, 0)\) and the focus is at \((0, 0)\). The vertex is the midpoint between the focus and the directrix.

### Step 2: Determine the Orientation of the Parabola
Since the focus is to the right of the vertex, the parabola opens to the right.
