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)}

D. is the answer

Step-by-step 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
