Replace the inequality sign with an equal sign.
Math Example
Let’s make sure you know the process for graphing quadratic inequalities. Can you correctly order the 5 steps of graphing quadratic inequalities?
Use the W and S keys to move arrange the items up or down.
Graph the parabola.
Look at the inequality that was in the original problem. If it’s ≥ or ≤, use a solid line to draw the parabola. If it’s > or <, use a dotted line.
Shade above the parabola for > or ≥ and below the parabola for < or ≤.
Check your work by choosing any point inside the shaded region and substituting back into the original inequality. If your work is correct, you will get a true statement.
You got it!
