Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! Find the vertex and equation of the directrix
for the following parabola y^2=-32x
----
Form y^2 = 4px
---
4p = -32
p = -8 means the vertex and the directrix are 8
units away from the vertex.
---
the vertex is at (0,0)
the equation produces a parabola that opens to the right.
-----
Vertex at (8,0)
Directrix: x = -8
