Exponential functions are frequently used to solve mathematical problems that can be sometimes involved. The operations of exponential functions and their use are mentioned in some of the examples. The properties of exponential functions can be seen with the use of their graphs.

Euler’s number is commonly used in advanced mathematics course and physical science disciplines because most solutions depend on it. Sample problems of the use of the basic exponential function are shown through the examples.
