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 shading a trapezoid?

    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  ?

    Simply change the = to >=.

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

    Example:

    2x+7-5x=27

    ??

    @Equaser_Shutter Your function can be simplified to "y ≤ -|3(x - 5/2)| + 51/6 {1 ≤ y ≤4}." Like this, when using a negative absolute linear function with restriction of y, you can insert the function really efficiently.

    Can you add restrictions to points? If so, how?
