Step-by-step explanation:

The standard equation of a parabola with vertex at the origin and vertical orientation is 4py = x2, where p is the distance between the vertex and the origin. When the vertex is not at the origin, but at the point (h, k), the standard form of the equation of the parabola is 4p(y – k) = (x – h)2.
