Question 188790: write the equation of a parabola with vertex (0,0) and focus (0,-2)
Answer by feliz1965(151) (Show Source): You can put this solution on YOUR website!
The focus lies 2 units below the vertex, so p = - 2 and the parabola is vertical. The endpoints of the focal chord lie | 2 p | units from the focus at right angles to the axis of the parabola, so they are at points ( - 4, - 2 ) and ( 4, - 2 ).
x^2 = -8y
