Primary Learning Objective(s):

Students will identify the order of operations in an algebraic statement and will be able to reverse (or undo) the operations.

Students will be able to find domain and range values of a function and will recognize that the domain and range values of the inverse function will be in reverse order (range becomes domain and vice versa).
