Big Ideas: An exponential function can be represented with a graph, table, or a written description. We can compare different exponential functions by showing all functions in the same form. Students are given 4 different pay scenarios (as in lessons 1-5) that are represented in a variety of ways, and students must write function rules for each of them. Students then compare all four scenarios and develop an argument that shows why a plan is most beneficial for the company or the employee. Vocabulary: exponential growth, exponential decay, common factor, exponential function
