Function Tables a Graphing

Which of the function(s) above are linear?

• Function I, only

• Function II, only

• Function I and Function II, only

• Function I, Function II, and Function III

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 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 table(s) represent linear functions?

• Table 1, only

• Tables 1 and 2, only

• Tables 1 and 3, only

• Tables 1, 2 and 3.

Which equation matches the table?

• y = 3x + 9

• y = x + 9 

• y = x + 3

• y = 12x - 3
