Function vs Not a Function Tables

Is this graph a function or not a function? 

• Function

• Not a Function

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 table(s) represent linear functions?
