Below are sample questions representative of the exercises included on this worksheet and related 8.98 Evaluating a Function for Given Inputs skill assessments:

Problem 1Difficulty: Hard
A game gives 120 starting coins and then adds 14.5 coins for each completed level l. The rule is V(l) = 14.5l + 120. What output does the function give for input 9?
Solution & Explanation:Substitute 9 for l: V(9) = 14.5(9) + 120 = 250.5. So the function output is 250.5.
Problem 2Difficulty: Hard
Choose the output when input 7 goes through function U. The rule is to square the input, add 1, and then divide by 2.
A25
B21
C24
D28
Solution & Explanation:Square 7 to get 49, add 1 to get 50, and divide by 2 to get 25. That gives 25, so the correct choice is A. 25.
Problem 3Difficulty: Hard
A museum charges $6.50 for each student s and adds a $14 transportation fee. The function is T(s) = 6.5s + 14. Which choice gives the output for input 6?
A39
B46
C53
D58
Solution & Explanation:Replace s with 6 in the rule: T(6) = 6.5(6) + 14 = 53. So the correct choice is C. 53.
