This video tutorial covers exponential functions, including their definition, properties, and how to graph them. It explains the difference between exponential growth and decay, and provides examples of each. The video also discusses the characteristics of exponential graphs, such as y-intercepts and asymptotes, and explores real-life applications like population growth and radioactive decay. Additionally, it highlights the symmetry in exponential functions and encourages viewers to practice graphing without a calculator.

• The base is greater than 1

• The base is between 0 and 1

• The base is equal to 1

• The base is less than 0
