Problem 83
Solve each inequality using a graphing utility. Graph each of the three parts
of the inequality separately in the same viewing rectangle. The solution set
consists of all values of \(x\) for which the graph of the linear function in
the middle lies between the graphs of the constant functions on the left and
the right.

Problem 88
Determine whether each statement "makes sense" or "does not make sense" and explain your reasoning. I've noticed that when solving some compound inequalities with or, there is no way to express the solution set using a single interval, but this does not happen with and compound inequalities.
Problem 103
Describe how to solve an absolute value inequality of the form \(|u|>c\) for \(c>0\)
