Step-by-step explanation:

I don't know the detailed options, but the answer in general is

the mapping of A to B is not a function, because at least one element of A (-2) is mapped to more than 1 element of B (1 and -4).

for a function every element of the domain can have 1 and only one assigned element of the range.

No its not a function

  • See -2 has 2 values in range.

As an element of domain doesn't have unique range (-2)

  • It's a relation
  • It's not a function
