Absolute value functions
Absolute value functions
Absolute value is basically the distance between “number” and “zero” on a number line. We will look into this concept in this lesson. We will also learn how to express absolute value functions as piecewise functions.

Notes:
Definition of “Absolute Value”:  number  = distance between “ number ” and “zero”

2.
Express the absolute value function as a piecewise function: $g\left( x \right) = \left {5  4x} \right$
