n

Answer 1

Answer:

NONE

Step-by-step explanation:

Functions do not repeat the first element of an ordered pair, relations do.

For instance the option A repeats the first element, the number 4 twice (4,0), (4,8)

option B repeats the first element, the number -4 twice (-4,9), (-4,8)

option C repeats the first element, the number -1 twice (-1,0), (-1,8)
