Diagram C.

Not a function

Diagram C. is the correct mapping for this relation.

It is, however, not a function.

A relation can be called a function if each element of the domain is related to exactly one element in the range.

We see from the diagram that both #4# and #1# are related to two different elements.

Therefore, this relation is not a function.
