Graphing and Solving Inequalities

Check if the quadratic inequality is inclusive or strict. Graph the parabola y = f(x) for the quadratic inequality f(x) ≤ 0 or f(x) ≥ 0. Find the vertex and identify the values of x for which the part of the parabola will either be negative or positive depending on the inequalities.

Graphing Quadratic Inequalities

High school students plot x-intercepts, figure out the axis of symmetry and the vertex of the parabola, determine the direction, and illustrate the inequality using dotted or solid lines. Shade the parabola below or above the x-axis, inside or outside the parabola based on the solution.
