Step-by-step explanation:
Since we have a vertical directrix, the equation of the parabola is
Where p is the distance from the vertex to the directrix.
or the distance from the vertex to the focus.
Since we have a sideways parabola, let use the point for the directrix is (-6,0). So let find the midpoint of (-6,0) and (6,0). That would be our vertex.
So our vertex is (0,0).
So our equation become
The distance from the focus and directrix is 6.
So p=6.
So p is 6.
Since p is 6,
