Vertex of a Parabola. A parabola is the shape defined by a quadratic equation. The vertex is the peak in the curve as shown on the right. The peak will be pointing either downwards or upwards depending on the sign of the x 2 term..

This is sometimes known as vertex form and we're not gonna focus on how do you get from one of these other forms to a vertex form in this video, we'll do that in future videos, but what we're going to do is appreciate why this is called vertex form. Now to start, let's just remind ourselves what a vertex is.
