The correct answer is the final data set: { (-4,-3), (0, - 3), (1, - 3), (4, - 3) }

Step-by-step explanation:

Functions are determined by the x values, which all have to be different. If the same x value appears twice and has a different y value, it is not a function, but if it appears twice with the same y value also, then it is. You can have the same y value twice, but not the x value unless it has the same y value, making the pair exactly the same. Those are the features of a relation being a function. I hope I said that to where it makes sense. Message me if you need clarification.
