4-9 Quadratic Systems

Objectives

To solve and graph systems of linear and quadratic equations

To solve and graph systems of quadratic inequalities

A solve it problem.
Image Long Description

By drawing a second parabola in the Solve It, you created a quadratic system.

Essential Understanding You can solve systems involving quadratic equations using methods similar to the ones used to solve systems of linear equations.

The points where the graphs of the equations intersect represent the solutions of a system.
