parabola with vertex at (0,0) and directrix at x=-3
Given parabola opens rightward.
Its basic form of equation: (y-k)^2=4p(x-h), (h,k)=(x,y) coordinates of the vertex
given vertex: (0,0)
axis of symmetry: y=0
p=3 (distance from vertex to directrix on the axis of symmetry
4p=12
Equation of given parabola: y^2=12x
