Answer

Graph attached.

Work Step by Step

To graph an inequality, first pretend like the equation given has an equal sign instead of an inequality symbol. Then, graph the equation. Next, shade the region of the graph containing points that result in true statements when plugged into the inequality. Finally, if the inequality is strictly less than or greater than (rather than having an equal sign under it), then dash the line drawn. We repeat this for all functions in the inequality. The area shaded in black is the solution to the entire inequality.
