which is the equation of a parabola with Vertex (0,0) and focus (-3,0)?
**
Basic equation of a parabola that opens downward: (x-h)^2=-4p(y-k), (h,k)=(x,y) coordinates of the vertex.
For given parabola:
vertex: (0,0)
axis of symmetry: x=0
p=3 (distance from vertex to focus on the axis of symmetry)
4p=12
equation of given parabola: x^2=-12y
