Graphing Inequalities

Adding colored shading to your Desmos graphs is easy with inequalities. Use < and > for strict inequalities (dotted line), and <= or >= for non-strict inequalities (solid line). Check out the video below for a quick demo.

Now that you know the basics, kick your shading skills up a notch! Here are some creative uses of inequalities for some graphing inspiration. What can you create?
