First you need to find the equation of the parabola, where based on the data is
in the standard form:%28y-y%5B0%5D%29%5E2=4c%28x-x%5B0%5D%29, and directrix x=-c or c=9.
Since its vertex is (-3, -6) the equation will be:%28y%2B6%29%5E2=36%28x%2B3%29
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.
