• (2,1), (2,2), (4,3), (4,4), (6,5), (6,6), (8,5)

Determine if the image represents a function.

• Yes, because there are the same amount of numbers in the input and output ovals.

• No, because you can not have an output of 0.

• Yes, because each input has only one output.

• No, because all arrows should be diagonal. The 4 arrow going straight across to the 6 fails the test.

Does the mapping diagram represent a function?  Explain your reasoning.

• Yes it is a function because every input has only one output.

• No it is not a function because every input has only one output.

• It is not a function because the input of 2 has two outputs.

• It is not a function because the input of 5 has two outputs.

Determine if the image represents a function.

• Yes, because each input has only one output.

• No, because each input has only one output.

• Yes, because there are 4 input numbers and 4 output numbers.

• No, because the input of 2 has two different outputs.
