Find the equation of the parabola with vertex (0,0) and focus (3,0).

Explanation

To find the equation of the parabola with vertex (0,0) and focus (3,0), we can follow these steps:

### Step 1: Identify the vertex and focus
The vertex of the parabola is given as (0,0) and the focus is given as (3,0).

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