write an equation of a parabola with its vertex at the origin and the given characteristics
focus at (0,-2)
***
Given parabola opens down with vertex at (0,0)
axis of symmetry:x=0 or y-axis
Its basic form of equation:x^2=-4py
p=2 (distance from vertex to focus on the axis of symmetry)
4p=8
equation of given parabola:
x^2=-8y
