A parabola equation has the parent equation of y=x^2 and the standard form of y=ax^2+bx+c. An example of a parabola could be y=x^2+1. What is a parabola in simple terms? A parabola is a curve in which every point on the curve is equidistant from a point called a focus and...
The equation for a leftward-opening parabola (the focus is to the left of the vertex) is(y−k)2=−4p(x−h). In all four forms,pis the focal length and (h,k) is the vertex. So, the first step in how to find the equation of a parabola is to determine the orientation. Fo...

The vertex of this parabola is (−1,3). Made using Desmos When written in vertex form, y=a(x−h)2+k the vertex is simply (h,k). If we have the equation in the form of y=ax2+bx+c we can calculate the x-value for the vertex, namely h, very easily: h=−b2a To ...
