A parabola has its vertex at the origin. It has a focal length measuring $a=4$a=4 units, and its focus lies on the $x$x-axis.

State both possible equations of the parabola.

Find the equation of the parabola with a focus at $\left(0,3\right)$(0,3) and a vertex at the origin. Let $a$a represent the focal length if necessary.

Find the equation of the parabola with a focus at $\left(-6,0\right)$(6,0) and a vertex at the origin. Let $a$a represent the focal length if necessary.
