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.. For more on quadratic equations and the parabolas they define see Quadratic Explorer where you can experiment with the equation and see the effects on the resulting ...
