Answer:

  A, C

Step-by-step explanation:

The lists of first numbers of the ordered pairs in each set are ...

  A: 1, 5, 8 . . . . . . unique, this is a function

  B: 1, 5, 5. . . . . . .not unique; not a function

  C: 1, 49, 52 . . . unique, this is a function

A function cannot have multiple outputs for the same input. For relation B, the input of 5 gives outputs of 'a' and 'c', so it is not a function.
