Connecting Graphing and Solving Absolute Value Equations and Functions

This Connecting Graphing and Solving Absolute Value Equations and Functions lesson plan also includes:

Can you solve an equation graphically? Absolutely! This Algebra II lesson makes the connection between solving an absolute value equation and graphing two functions. Graphing absolute value functions is presented through the process of transformations of the parent function. Solving absolute value equations is explored as graphing a system of two functions and finding the intersections.
