Find the focus and directrix of the parabola with the given equation. Then graph the parabola. y^=-12x ** y^2=-12x This is an equation of a parabola with a horizontal axis of symmetry. Its standard form: (y-k)^2=4p(x-h), with (h,k) being the (x,y) coordinates of the vertex. For given equation:
Vertex(0,0) 4p=12 p=3 Focus:(-3,0) Directrix: x=3 see the graph below as a visual check on the answers: .. y=±(-12x)^.5
