Linear and Exponential Functions Concepts

The video tutorial covers linear, quadratic, and exponential models, explaining their equations and characteristics. It demonstrates how to graph these functions and identify them using data sets. The tutorial also includes practical examples of modeling real-world data, emphasizing the use of differences and ratios to determine the appropriate function type.
