A parabola is defined as a curve where each point is equidistant from:
fixed point (focus) and
fixed line (director).
The properties of a parabola can be defined as given below:
Rays parallel to the axis of symmetry are reflected straight from the surface to the focal point.
Because the vertex of the parabola is at (0,0) and the focus is at (-3,0).
This means that the parabola axis is the negative x-axis.
The parabola equation is x^2 =4ay and a=3.
So, the parabola equation is x^2 =12y.
