Expert Answer
The vertex is the origin and the focus is (0,-2) which lies on the y - axis. Here a = -2, hence the parabola is of the form x2 = -4ay.
Hence the equation of the parabola is x2 = -8y.
Alert ! The negative sign is the formula x2 = -4ay signifies that it is a downwoard parabola. Take a = 2, as the negative sigin is already considered in the formula.
