Jaun, I would first figure out where the focus is. The directrix is x=-c in which is the same distance as the focus from the vertex of the parabola, and it opens to the right.
c=1/4a=1/4(32) = 1/128 Hence, the focus is at (1/128,0)
This implies the directrix is x=-1/128.
The axis of the parabola is y=0.
