Step-by-step explanation:
We want to find the equation of a parabola withfocus at (-3,0) and directrix y=3.
This para has its vertex at the origin and opens downward.
The equation is of the form
Where p is the distance from the vertex to the focus.
This distance is p=|0-3|=3
We substitute p=3 to obtain:
Hence the equation is
