Students will learn how to graph the absolute value function under various transformations. They'll do this for both absolute value equations and inequalities. Students will also learn how to find an absolute value equation from its graphs. They'll do this for inequalities too. After that, students will learn how to identify absolute value equations from the function's intercepts. When given the intercepts, students will graph the function, then determine the equation from the graph.
