Is the table on the right a function? 

• No, because not every input has exactly one outout

• Yes, because every input has exactly one output 

• No, because 4 has more than one output

This table corresponds to inputs and outputs. Could this represent a function rule? Select the correct answer and the correct reason.

• Function because each input has one output.

• Not a function because each input has one output

• Function because the input -2 has two different outputs.

• Not a function because the input -2 has two different outputs.
