Understanding Linear and Exponential Functions

The video tutorial explains how to determine if a table represents a linear, exponential, or neither function. It describes the characteristics of linear functions, which have a common difference, and exponential functions, which have a common ratio. The tutorial provides examples of each type and demonstrates how to analyze tables to identify the function type. It concludes with a graphical representation of the functions.

What is the form of a linear function?

• f(x) = ax^2 + bx + c

• f(x) = a/x

• f(x) = mx + b

• f(x) = a * b^x
