Functions Involving e (Part 2)

In part 1, a warm-up problem involving compound interest discusses where the number e, the natural number ~2.718, comes from. Other examples show how to simplify expressions with e using exponent rules, and evaluate expressions with e using the calculator. In part 2, exponential growth versus decay is discussed when e is the base (common multiplier), and a number of examples of graphing exponential functions are given. In part 3, continuously compounded interest is discussed: A=Pe^(rt), and an example is shown.
