Exponential Growth and Decay Concepts

The video tutorial covers exponential growth and decay, explaining the equation y = a * b^x, where 'a' is the initial value and 'b' is the growth or decay factor. It provides examples, including a car's value decreasing over time, and guides students through practice problems using tables of values.
