Does this relation represent a function?

• No

• Yes

Is this table a function or not a function? 

• Function

• Not a Function

Is the relation a function?

• yes, it is a function

• no, it is not a function

• not enough information to determine

Which of the following is not a function?

• {(0,1), (1,2), (2,3), (3,4)}

• {(0,2), (1,3), (4,3), (1,2)}

• {(1,3), (4,2), (2,0), (3,4)}

• {(1,2), (2,2), (3,2), (4,2)}

Is this mapping 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.
