The parabola has focus (–8, 0) and vertex at the origin

  x = -1/32y^2

Step-by-step explanation:

Since the focus is to the left of the vertex at a distance of 8 units, the equation can be written as ...

  x -h = 1/(4p)(y -k)^2 . . . . with vertex-focus distance of p and vertex (h, k)

  x = -1/32y^2
