Question

Which set of ordered pairs represents y as a function of x?

Please answer my question

A. {(2,2), (3,3), (2,4), (5,5)}


B. {(−1,−2), (−2,−1), (−2,7), (−4,8)}


C. {(−1,6), (4,3), (1,1), (−3,4)}


D. {(0,1), (2,1), (3,1), (0,2)}

Answer 1

C.

Explanation:

The set of ordered pairs can only be a function if the x value is not repeated .Thus,only C is a function as the x values (-1,4,1,-3) are unique while the other options have a repetition of its certain x values.
