Use the distance formula to write an equation of the parabola. focus: (0,2) directrix: y=-2

y = (x^2)/8

Step-by-step explanation:

This is a vertical parabola.  Because the y-coordinate of the focus is greater than the y-value of the directrix, the graph opens up.  The general formula for a parabola in this situation is 4py = x^2.  Here, y is the distance between the vertex (0,0) and the focus, or 2.  Thus, 4(2)y = x^2, or y = (x^2)/8.
