Question

Which set of ordered pairs represents a function?

Select one:
a. {(0, 1), (1, 3), (1, 5), (2, 8)}
b. {(0, 0), (1, 2), (2, 6), (2, 8)}
c. {(0, 0), (0, 2), (2, 0), (2, 4)}
d. {(0, 2), (1, 4), (2, 6), (3, 6)}

Answer 1

the answer is D because the x values repeat in the other choices

Answer 2

D. is the answer

Explanation:

A. is not a function because x = 1 produces y = 3 and y = 5

B. is not a function because x = 2 produces y = 6 and y = 8

C. is not a function because x = 2 produces y = 0 and y = 4

D. is a function Since there is one value of y for every value of x
