Which set of ordered pairs is not a function? a. (4, –2), (–2, 2), (2, –2), (4, 2) b. (–4, 2), (–2, 2), (2, 2), (4, 2) c. (–4, 2), (–2, –2), (2, 2), (4, 2) d. (–4, –2), (–2, –2), (2, 2), (4, 2)

  A. (4, –2), (–2, 2), (2, –2), (4, 2)

Step-by-step explanation:

If the same input value shows up more than once, the relation is not a function. In the above answer choice, 4 shows up twice as an input value.

All the other answer choices have inputs of -4, -2, 2, 4, with no repeats.

the perimeter is increased by a factor of 2

i think this could be a possible answer (1 / 84) -1

good luck! : d
