Question

(HELP MY TEACHER WANTS ME TO PASS THIS!) The partial set {(1, 2), (8, –6), (–6, 1), (13, 13)} is a function. Which ordered pair must be added to this set in order for it to remain a function?
a. (13, 0)
B. (–6, 8)
C. (1, 7)
D. (2, 2)

Answer 1

A function cannot have the same number of ‘x’ repeated in ordered pairs, so therefore the answer would be D, (2,2) because the x wouldn’t repeat.
