Creating and Graphing Exponential Relationships

The video tutorial introduces exponential growth and decay, explaining how to create and graph exponential relationships using exponential functions. It provides an example with dots to demonstrate exponential growth, explains the formula y = a(1 + r)^x, and discusses graphing exponential functions. The tutorial also highlights common mistakes in exponential calculations and solves a problem on US population growth using exponential functions.

What does the variable 'r' represent in the exponential growth formula?

How do you graph exponential functions, and what do you expect to see?

What is the growth rate of the US population mentioned in the lesson?
