the equation of the parabola with
a vertex at the origin: (,)
and a focus at :(,).
the absolute value of is the distance between the vertex and the focus :
The focus is at (, )
=>
=>
=>
Since this is a "downward" parabola, then the part gets squared, rather than the part. So the conics form of the equation must be:
