Using it's concept, the set of ordered pairs that represent a function are:

  • (2, 3), (6,-5), (-1, 3)
  • (7.-4), (0, 9), (2,-2)
  • (-6, 5), (-5, 6), (8, 2)

The set of ordered pairs that do not represent a function are:

  • (1,9), (-3,-2) (1,-4)
  • (0, 3), (0, 7), (4,0)

When does a relation represents a function?

A relation represents a function if each input X is mapped to only one output Y.

At (1,9), (-3,-2) (1,-4), input 1 is mapped to outputs 9 and -4, hence it is not a function.

At (0, 3), (0, 7), (4,0), input 0 is mapped to outputs 3 and 7, hence it is not a function.

For the other relations, each input is mapped to only one output, hence they are functions.
