1.9.1: Piecewise-Defined Functions
In preparation for the definition of the absolute value function, it is extremely important to have a good grasp of the concept of a piecewise-defined function.
1.9.2: Absolute Value
The absolute value of a number is a measure of its magnitude, sans (without) its sign.
1.9.3: Absolute Value Equations
1.9.4: Absolute Value Inequalities
