Answer 1

The mapping diagram above **does not represent** a function since **an element in Set A can be mapped to more than one element in Set B** where there **is no unique output for each input**.

For example, if the number 3 from Set A is mapped to both -1 and 5 in Set B, this violates the definition of a function, which states that each input must map to exactly one output.
