Linear and Nonlinear Functions Graphs

Which graph is NOT a function?

• A

• B

• C

• D

Which answer choice is true?

• The table represents a linear function because there is a pattern for the x-coordinates and y-coordinates.

• The table represents a linear function because the ratio of the change in the y value and the change in the x value is constant.

• The table represents a nonlinear function because the ratio of the change in the y value and the change in the x value is not constant.

• The table does not represent a function because there is more than one output for at least one input.

Which table(s) represent nonlinear functions?

• Table 1, only.

• Table 2, only

• Tables 1 and 3, only

• Tables 2 and 3, only

Which graph(s) show nonlinear functions?

• Graph I, only

• Graph II, only

• Graph I and Graph II, only.

• Graph I, Graph II, and Graph III

Which company shows a greater rate of change?

• Water's Edge Rafts

• Ryan's Rafts
