Which of the following lists of ordered pairs is a function?

D

Step-by-step explanation:

to be a function you cannot have different y values for the same x, in B for example when x = 3 you have two different values for y (3,7) and (3,8)

D is the only choice where each value of x only has one value for y

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
