The set that represents possible inputs and outputs of the function is  {(0, −7), (1, 2), (−1, −16)}

Given the function:

y = 9x - 7

We need to determine the input and outputs of the function. To do that, we will need to vary the input values to get the output values

If x = 0

y = 9(0) - 7

y = -7

If x = 1

y = 9(1) - 7

y = 9 - 7

y = 2

If x = -1

y = 9(-1) - 7

y = -9 - 7

y = -16

Hence the set that represents possible inputs and outputs of the function is  {(0, −7), (1, 2), (−1, −16)}
