OVERVIEW of lessons on plotting functions with Linear Terms under the Absolute Value sign
The plotting strategy is to break up the entire set of real numbers into sub-domains (ranges) where the absolute value of a linear term is a linear function,
and then to combine and to plot all these piecewise linear functions.
In order to break up the entire set of real numbers into sub-domains (ranges), where the absolute value of linear terms is a linear function,
you should analyze the function which is under the Absolute Value sign.
The referenced lessons contain all details on how to build these plots.
