Below are sample questions representative of the exercises included on this worksheet and related 8.108 Completing Function Tables skill assessments:

Problem 1Difficulty: Hard
A table is made by this rule: Add 5 to the input, then square the result. Input: 0, 2, 4, ?; Output: 25, 49, 81, 121. What replaces the question mark in the input row?
Solution & Explanation:The missing output is 121. Since (x + 5)2 = 121, x + 5 = 11, so x = 6. The missing input is 6.
Problem 2Difficulty: Hard
The input-output machine follows this rule: Multiply the input by -2, then add 11. Input: 0, 3, 6, ?; Output: 11, 5, -1, -7. Find the missing input.
Solution & Explanation:Work backward from the output -7. Subtract 11 to get -18, then divide by -2 to get 9. The missing input is 9.
Problem 3Difficulty: Hard
Use this rule to complete the table: Triple the input, then subtract 12. Input: 1, 4, 7, 10; Output: -9, 0, 9, ?. What number goes in the blank output cell?
Solution & Explanation:Apply the rule to the missing input 10. That gives 18, so the missing output is 18.
