Exploring Linear and Nonlinear Functions

The video tutorial covers linear and nonlinear functions, explaining their differences and how to identify them. It uses examples like a football's trajectory, table data, ticket sales, and the area of a square to illustrate these concepts. Linear functions have a constant rate of change, forming a straight line, while nonlinear functions do not, resulting in curves. The tutorial emphasizes understanding these concepts through real-world examples and data analysis.

What is the main characteristic of a linear function?

• It forms a zigzag pattern.

• It has a variable rate of change.

• It has a constant rate of change.

• It forms a curve.
