Sketch the following parabola. Indicate the vertex, focus and directive.
(The right side of the equation should be 12x not 12y)
Find the equation of the parabola that satisfy the given conditions:
5) focus (0,4) directrix y= -4
6) focus (2,0) vertex (0,0)
7) vertex (0,0) directrix x=-3/2
8) focus (0,-5) directrix y=5
