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
