Solution: The directrix of parabola is x + 5 = 0. The focus of the parabola is (a, 0) = (5, 0). For the parabola having the x-axis as the axis and the origin as the vertex, the equation of the parabola is y 2 = 4ax. Hence the equation of the parabola is y 2 = 4 (5)x, or y 2 = 20x. Therefore, the equation of the parabola is y 2 = 20x. Formula Used.
