How would you find the vertex p value focus directrix and focal width of negative one fourth x squared equals y?

-(1/4) x2 = y . . . putting this in the standard form x2 = 4cy it becomes :
x2 = 4*(-1)y = -4y.
This tells us that the parabola is a downward opening parabola with its vertex at the origin(0.0).
The focus is at a distance of -1 from the vertex, that is (0,-1).
The directrix is equidistant to the focus but on the opposite side of the vertex and is thus the line y = 1.
The length of the chord passing through the focus and perpendicular to the major axis is called the Latus Rectum and has a length of 4c. As c = -1 then the length is 4 but again shows as a negative value as it is "below" the vertex.

How does one half squared equal one fourth?
One half squared equals one fourth because when you multiply one half by one half you get one fourth. This is the equivalent of saying that half of one half is one fourth.
Why does negative one to the fourth power equal negative one?
It doesn't. Negative one to an even power equals positive one. Negative one to an odd power equals negative one.
