Understanding Linear and Exponential Functions

The video tutorial explains how to determine if a function is linear or exponential by analyzing patterns in function values. It describes the form of an exponential function and how to derive its equation using a table of values. The tutorial concludes with a graphical verification of the derived equation to ensure accuracy.

What indicates a linear function in a table of values?

• Constant x-values

• Repeated multiplication in function values

• Repeated addition in function values

• Decreasing y-values
