How do you find the vertex, focus and directrix of a parabola
rewrite equation into standard form: (y-k)^2=-4p(x-h)
This is an equation of a parabola that opens leftwards.
axis of symmetry: x-axis or y=0
focus(0,-9) (p distance left of vertex on the axis of symmetry)
directrix:(0,9) (p distance right of vertex on the axis of symmetry)
