The mapping shown represents a function.

Set A represents the domain, and all the elements in Set A (5, 9, -3) are mapped to unique elements in Set B (8, -1, -4).

There is no element in Set A that is mapped to multiple elements in Set B, which means each input in Set A has a unique output in Set B.

Therefore, the mapping shown represents a function.
