Topic

Quadratics

Description

In this example, the parabola has its focus at (0, 1) and directrix y = -2. The vertex is at (0, -0.5), and the parabola opens upward. The distance p from the vertex to the focus is 1.5. This example reinforces the relationship between the focus, directrix, and the resulting equation of the parabola.
