### Math Blogging, Part 2

Find the equation for each of the three parabolas for which the coordinates of the focus and the equation of the directrix are given. I kept getting incorrect answers, until I realized that the coordinates were of the focus, not the vertex.

Parabola 1

focus=-3,-2 y=-6

Parabola 2

focus+4,-3 y=6

Parabola 3

focus=4,0 x=-2

Parabola 1

focus=-3,-2 y=-6

Parabola 2

focus+4,-3 y=6

Parabola 3

focus=4,0 x=-2
