Identifying Functions Practice

Match the following relations to their respective statements.

• B

• This representation is not a function because the input of -3 has more than one output.

• E

• This representation is a function because it passes the vertical line test.

• F

• This representation is not a function because the input of 3 has more than one output.

• D

• If you added (7,3) to this representation, it would no longer be a function.

• A

• This representation is a function where each input has the same output.
