Identifying Functions Practice

Which statement about the mapping is true?

• The mapping represents a function because each input maps to one output.

• The mapping represents a function because each output maps to one input.

• The mapping does NOT represent a function because at least one input maps to more than one output.

• The mapping does NOT represent a function because at least one output maps to more than one input.
