How do you determine the vertex of a parabola
WebExample 1: Find the equation of a parabola having the directrix of parabola as x + 5 = 0, the x-axis as the axis of the parabola, and the origin as the vertex of the parabola. 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 … WebWhile the standard quadratic form is a x 2 + b x + c = y, the vertex form of a quadratic equation is y = a ( x − h) 2 + k.
