First you need to find the equation of the parabola, where based on the data is
in the standard form:, and directrix x=-c or c=9.
Since its vertex is (-3, -6) the equation will be:
This parabola opens right because c=9>0, the vertex is (-3, -6), the axis is the
line y=-6 , the focus is (9, -6) and the directrix x=9.
