    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

    y=± (-12x) ^.5
