Which of the sets of ordered pairs represents a function? a = {(−5, 5), (−2, 2), (2, −2), (5, −5)} b = {(4, 2), (3, −2), (9, 4), (11, −3)} only a only b both a and b neither a nor b
I think this is for a online school test, I suggest mastering the skill before moving on, a hint would be a function is a input that has one Y output f(2) = 4x+2 f(2) = 4(2) + 2 =8 + 2 = 10
