How it works ?
On a separate sheet of paper, solve the absolute value inequality that appears in the applet below.
Once you obtain your lower and upper boundary values, enter them in the input boxes. (Be sure to use exact values!) Then, use the sliders to adjust the inequality symbols and to create a conjunction or disjunction.
Once you enter your solution set correctly, you’ll see a big“Correct !!! “sign appear.
Repeat this exercise as many times as you need in order to master this concept!
