Does the mapping diagram represent a function? Explain.

• No; the input values (x-values) of 1 and 3 are both paired with the same output (y-value).

• No; there are more input values (x-values) than output values (y-values).

• Yes; each input (x-value) is paired with only one output (y-value).

• You can't tell if a relation is a function from a mapping.
