Answer 3

The mapping diagram above **does not represent** a function since **each element in Set A must map to exactly one element in Set B**, but in this case, **there are elements in Set A that map to multiple elements in Set B** (if that's implied from the interpretation of the mapping). In a function, each input (from Set A) should have one and only one output (in Set B).

Answer 4

The mapping diagram above **represents** a function since **each element in Set A** maps to **exactly one element in Set B** where there **are no elements in Set A that map to multiple elements in Set B**. In other words, every input has a unique output.

Answer 5

The mapping diagram above **does not represent** a function since **an element in Set A may map to more than one element in Set B** where there **is at least one input in Set A that has multiple outputs in Set B**. In a function, each input must correspond to exactly one output.
