You can put this solution on YOUR website! find the equation of a parabola given focus (-2,3) directrix y=-3
This is a parabola that opens upwards.
Its standard form of equation: (x-h)^2=4p(y-k), (h,k)=(x,y) coordinates of the vertex
vertex:(-2,0)
axis of symmetry: x=-2
p=3 (distance from vertex to focus or directrix on the axis of symmetry
4p=12
Equation of given parabola: (x+2)^2=12y
