Linear and Nonlinear Functions

• How to determine whether a function is linear or nonlinear.

Linear functions have constant rates of change. Their graphs are straight lines and their equations can be written in the form y = mx + b.

Nonlinear functions do not have constant rates of change and their graphs are not straight lines.

Tables can represent functions. A nonlinear function does not increase or decrease at a constant rate.

Determine whether the graph represents a linear or nonlinear function.

Determine whether the graph represents a linear or nonlinear function.

Determine whether the function represents a linear or nonlinear function.

y = -5x – 4

Determine whether the function represents a linear or nonlinear function.

y = 2x2 + 3
