Example 2

Derive the exponential function on which the logarithmic function is based.
  1. Switch the domain and function variables to write the logarithmic function as an exponential function.
  2. Use the rules of logarithms to rewrite the result so that the simplest expression possible can be found for the logarithmic function before it is converted to exponential form.
  3. Solve for the logarithmic term and rewrite the logarithmic function as an exponential function.
  4. Write the exponential function from the simplified logarithmic function by using the definition of an exponential function and its inverse.
