Question

Which set of ordered pairs represents a function?

Question 1 options:


{(5, 6), (2, 6), (-3, 4), (-1, 4)}


{(0, 0), (2, 3), (1, -4), (2, -2)}


{(-5, 1), (-4, 2), (-5, 3), (-4, 4)}


{(3, -2), (-4, -1), (0, 3), (0, 5)}

Answer 1

the first choice because the x variable is not repeating.

Answer 2

Answer: The answer would be the first choice.

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.
