Absolute Value Functions
Absolute value is defined as a number’s distance from zero. Since distance is always positive or zero, absolute value functions will always produce positive or zero outputs.Absolute value functions have equations in the form:

See the table and graph of a basic absolute value function below.

Here are some situations that can be modeled by absolute value functions:
- Distances in real life (time vs. distance).
- Exchanging currency (old currency vs. new).
