In a function machine, what do you call the number you start with?

• A. Output
• B. Input
• C. Result
• D. Exponent

Answer: (B)

The starting value in a function machine is called the input. It’s the number you feed into the rule inside the machine. The machine then processes that input to produce a new number, which is the output. For example, if the rule is “add 5” and you input 7, 7 is the input and the output is 12. An exponent is a power and isn’t the starting value in this context, and while a result describes what you get after applying the rule, the standard term for the number you begin with is input.
