# Lesson 30: Exponential Functions

Topic(s):

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.
