# Lesson 30: Exponential Functions

Course Topic(s): Developmental Math | Exponentials

Beginning with a formal definition of an exponential function, the lesson then compares the graphs of increasing and decreasing exponential functions. A comparison between exponential and power functions follows, which leads to methods for determining the (p) value in the power function (h(x) = kx^p) and the value of the base( b) in the exponential function (f(x) = ab^x). A procedure for solving exponential equations is presented before a population application problem is solved. The lesson concludes with a discussion about using graphs to find approximate solutions to exponential equations.
