A big topic in Algebra II is the study of Logarithms. Throughout the course, students learn to take inverses of functions, we start with inverses of linear equations, move to quadratics and eventually make our way to exponential functions. The activity below, shows students that even though they have not learned a way to take the inverse of an exponential function, the inverse exists. By the end of the activity, students will be able to:
  • Find the inverse of functions of the form y=b^x
  • Plot logarithmic functions
  • Describe transformations of a logarithmic function with respect to its parent function.
  • Algebraically write inverses of exponential functions and vice versa.
