Students study quadratic relationships and explore the process of graphing quadratic inequalities and systems of quadratic inequalities. They will solve these inequalities algebraically and graph them on a coordinate plane.

Install the Inequality Graphing Application on the calculator using one of these two methods:

• TI Connect™, a TI Connectivity Cable, and the Unit-to-Unit Link Cable
• TI-Navigator™ "send to class" feature

Distribute the pages to your class.

Follow the Activity procedures:

• Graph the equation y = x²
• Locate points and algebraically determine if they are part of the solution set of the inequality y > x²
• Observe that all the points that are part of the solution set lie inside the parabola y = x²
• Use the Inequality Graphing Application to graph the inequality and verify the observation
• Graph a system of quadratic inequalities
• Predict if the two inequalities intersect in one or more points
• Use the Inequality Graphing application to verify the prediction
• Use the Inequality Graphing application to graph another system of quadratic inequalities

Students will complete the Student Worksheet and answer questions.
