Exponential Functions and Their Properties

The video tutorial explains the concepts of exponential growth and decay. It begins with an introduction to these concepts, followed by a detailed example of exponential growth using the function y = 2^x. The tutorial then explores exponential decay with the function g(x) = (1/2)^x, highlighting the differences between growth and decay. The video concludes with a comparison of the two functions, emphasizing the properties of exponential functions and their behavior as x values change.

What is the main focus of the video tutorial?

• Exponential growth and decay

• Quadratic functions

• Linear equations

• Trigonometric identities
