Graphing Quadratic Inequalities - Boundary Curves and Test Points

How to graph a quadratic inequality in two variables. Step 1. Identify and graph the boundary curve (parabola). Key formulas include expressions such as \leq. This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 3: Quadratic Equations and Complex Numbers.

Key Concepts

How to graph a quadratic inequality in two variables. Step 1. Identify and graph the boundary curve (parabola). If the inequality is $\leq$ or $\geq$, the boundary curve is solid. If the inequality is $<$ or $ $, the boundary curve is dashed. Step 2. Test a point that is not on the boundary curve. Is it a solution of the inequality? Step 3. Shade in one side of the boundary curve. If the test point is a solution, shade in the region that includes the point. If the test point is not a solution, shade in the opposite region.
