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 □ 2 □ 4 □
output 4 16 11 12 15 20 9
available numbers: 1, 2, 3, 4, 5, 6, 7

Explanation:

Step1: Recall function definition

A function requires each input (x-value) to have exactly one output (y-value), but outputs can repeat for different inputs. Existing unique inputs: 1, 7, 2, 4.

Step2: Fill first empty input

Choose a number not already used as an input (to avoid conflicts). Available numbers: 3,5,6. Assign 3 to pair with output 11.

Step3: Fill second empty input

Choose another unused number. Assign 5 to pair with output 15.

Step4: Fill third empty input

Assign the last unused number. Assign 6 to pair with output 9.

Answer:

Input	1	7	3	2	5	4	6

(Note: Any unused numbers from {3,5,6} can be assigned to the empty input slots, as long as no input value repeats.)
