The answer is the second choice.

There cannot be repetitive domains in one set. Therefore, all choices except the second choice have repetitive domains.

Thus, not making them a function but rather a relation instead for other choices. The only relation that is a function here is the second choice.

the second one because the x values should not have repeating numbers
