Understanding Linear and Exponential Functions

The video tutorial explains how to fill in missing function values in tables and determine if they represent linear or exponential functions. It highlights the difference between repeated addition (linear) and repeated multiplication (exponential). The first table shows exponential growth with a multiplier of five, while the second table shows exponential decay with a multiplier of one-fourth. The video also demonstrates how to graph these functions, showing exponential growth and decay curves.

What does a pattern of repeated addition in function values indicate?

• An exponential function

• A logarithmic function

• A linear function

• A quadratic function
