Find the equation of the parabola that satisfies the given conditions:Focus `(0, -3)`; directrix `y = 3`

Text Solution

Verified by Experts

Focus `(0,-3)`
Directrix `y=3`
Since the focus lies on the y-axis, the y-axis is the axis of the parabola.
Therefore, the equation of the parabola is either of the form `x^2=4ay` or `x^2=-4ay`
