Question

consider the table of input and output values shown. drag a number to each box to complete the table of values to represent a function.
input: 1, 7, blank, 2, blank, 4, blank
output: 4, 16, 11, 12, 15, 20, 9
available numbers: 1, 2, 3, 4, 5, 6, 7

Explanation:

Step1: Recall function definition

A function assigns exactly one output to each input, so each input value can only appear once.

Step2: Match outputs to new inputs

First, find input for output 11: available inputs are 3,5,6. Choose any unused input, e.g., 3.

Step3: Match next output to input

For output 15: pick another unused input, e.g., 5.

Step4: Match last output to input

For output 9: use the remaining unused input, 6.

Answer:

Input row (empty boxes left to right): 3, 5, 6
(Note: Any combination of unused unique inputs (3,5,6) in the empty boxes is valid, as long as no input repeats.)
