Question

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

Select TWO correct answers.

A.
{(0, 0.5), (2, 1.5), (−5.5, 5), (−5.5, −6)}
B.
{(5, −7), (3, −7), (−9.2, −7), (9.2, −7)}
C.
{(9.3, −1), (7.3, −2), (7.3, 2), (9.3, 1)}
D.
{(8.1, 9), (9.1, 10), (10.1, 9), (9.1, 8)}
E.{(11.1, 9), (5.1, 6), (12.1, 7), (6.1, 9)}

Answer 1

B. {(5, -7), (3, -7), (-9.2, -7), (9.2, -7)}

E. {(11.1, 9), (5.1, 6), (12.1, 7), (6.1, 9)}

Explanation:

The sets that represent y as a function of x are those where each x-value is associated with a unique y-value. Therefore, the correct answers are: B and E.

In both options B and E, each x-value is associated with a single, unique y-value, making them functions.
