Answer:

  • First mapping is a function because there is no more than one output for each input.
  • Second mapping is not a function because there is more than one output for input B.
  • Third mapping is a function because there is no more than one output for each input.
  • Fourth mapping is a function because there is more than one output for each input.

Explanation:

A function can be defined as two variables (independent and dependent) which cannot have more than one output for each input.
