It is a function

Domain: 17, 15/4, 15, 17/4

Range: 15/4, 17, 17/4, 15

Step-by-step explanation:

3) For an ordered pair to be a function, it must have only one input and only one output.

An input must not have more than one output.

From what we are given: (17, 15/4), (15,4, 17), (15, 17/4), (17/4, 15)

There is only one output for each of the input. None of the numbers in the input appeared twice in the domain.

Hence, the set of ordered pair is a function

Domain are the x values of a function. They are also referred as the input.

The input are the first numbers in an ordered pair.

Domain: 17, 15/4, 15, 17/4

Range are the y values of a function. They are also referred as the output.

The output are the second numbers in an ordered pair.

Range: 15/4, 17, 17/4, 15
