Linear and Nonlinear Functions

Which is the definition of a LINEAR FUNCTION?

• The graph is a line that is vertical

• The graph is a line that is not vertical

• The graph is a line that is only horizontal

• The graph is not a line

A nonlinear function DOES NOT have a constant rate of change?

• True

• False

Is this a linear or nonlinear function? Why or why not?

• Linear because there is a constant rate of change.

• Linear because there is not a constant rate of change.

• Nonlinear because there is not a constant rate of change.
