Be able to....
1. Determine whether a relation is a function and if it's a function, whether the function is one-to-one. Relations can be presented as a list of ordered pairs, a table, a graph, or a mapping diagram.
2. Find the inverse of a relation. Relation can be presented as a list of ordered pairs, a table, a mapping diagram, or an equation.
3. Use composition to verify that 2 equations are inverses.
4. Solve absolute value equations.
5. Solve absolute value inequalities. Must be able to give solution in interval or inequality notation AND graph solution on a number line.
6. Graph absolute value equations and name the vertex, domain, range, increasing interval, decreasing interval, and describe the transformations.
7. Graph a piecewise function given the equation.
8. Rewrite an absolute value equation as a piecewise equation.
9. Evaluate piecewise equations for a given value.
10. Write and use a piecewise function model.
11. Given the graph of a piecewise function, write the equation.
