Section 12 Absolute Value Functions

**Lesson: Absolute Value Expressions and Equations**

Major Emphasis:

L1.1.2 Interpret representations that reflect absolute value relationships.

**A1.2.4** Solve absolute value equations and inequalities and justify steps in the solution.

**Lesson: Absolute Value Functions: Transformations, Domain and Range**

A2.2.2 Apply given transformations to parent functions and represent symbolically.

**Lesson: Absolute Value Piecewise Functions**

A2.1.4 Recognize that functions may be defined by different expressions over different intervals of their domains. Such functions are piecewise-defined.

**Lesson: Advanced Absolute Value Equations - Extraneous Solutions**

Major Emphasis:

L1.1.2 Interpret representations that reflect absolute value relationships.

**A1.2.4** Solve absolute value equations and inequalities and justify steps in the solution.

**Also Addressed:**

Solve power equations and equations including radical expressions, justify steps in the solution, and explain how extraneous solutions may arise.
