Parabola equation given focus and directrix

WebMar 21, 2024 · How to Find the Equation of a Parabola? We can easily find the equation of a parabola if the focus and directrix of a parabola are given by using the below steps:. Step 1: Determine the orientation of the parabola using the directrix of a parabola. If the equation of the directrix of a parabola is of the form \(y = b\), for some number \(b\), then the … WebHow To: Given its focus and directrix, write the equation for a parabola in standard form. Determine whether the axis of symmetry is the x – or y -axis. If the given coordinates of the focus have the form (p,0) ( p, 0), then the axis of symmetry is the x -axis. Use the standard form y2 =4px y 2 = 4 p x.
