Question

Which set of ordered pairs represents a function?

Answer 1

Answer: The answer would be the first choice.

Step-by-step explanation:

Remember that a function is where every INPUT has exactly ONE OUTPUT. That means for the coordinates (x, y), no pair could have an x value repeat. So, the first ordered row pair does not have any repeating x values, so it's the first answer.

Answer 2

The first choice because the x variable is not repeating.
