Inequalities

Overview

With inequalities, you can add colored shading to your Desmos graph. Use strict inequalities (< and >) for dotted lines and non-strict inequalities (<= or >=) for a solid line. 

 

 

For more intricate graphs, you can also use inequalities with restrictions to shade selected parts of the graph.

    Some graphs I have seen have equations that look something like this: F={x>a:mod(x,a)}. What does that mean? (the mod function is just an example, I know what modulo does)

    how would you go about moving this shaded circle upwards or shading a circle with the equation of (x-k)^2+(y-h)^2=r^2  ?

    How do we solve inequalities in number format in the scientific calculator.

    Example:

    2x+7-5x=27

    ??
