Graphing Systems of Quadratic Inequalities

Sketch the solution to a system of quadratic inequalities by graphing each parabola, testing points, and shading the overlapping region.


What You'll Learn

A system of quadratic inequalities is solved by graphing each parabola as a boundary and shading the region that satisfies each inequality on its own
Use a dashed curve for strict inequalities (less than or greater than) and a solid curve for inequalities that include equality
A test point that is not on either curve tells you which side of each parabola to shade
The solution to the system is only the area where the two shaded regions overlap
Finding where the two parabolas intersect algebraically helps you see the exact boundary of the overlapping region

What You'll Practice

1

Graphing two quadratic inequalities on the same coordinate plane

2

Shading regions above and below parabolas based on inequality signs

3

Identifying overlapping solution regions for systems

4

Checking answers by substituting test points into both inequalities

Why This Matters

Graphing systems of quadratic inequalities builds your ability to solve complex real-world optimization problems involving multiple constraints, such as business profit regions, engineering design limits, and physics applications where multiple conditions must be satisfied simultaneously.
