Evidence Statement Text:

Relate the domain of a function to a graph and, where applicable, to the quantitative relationship it describes, limiting to linear functions, square root functions, cube root functions, piecewise-defined functions (including step functions and absolute-value functions), and exponential functions with domains in the integers. For example, if the function h(n) gives the number of person-hours it takes to assemble n engines in a factory, then the positive integers would be an appropriate domain for this function.★

1. Paper Test, Unit 2, Item 25
A local theater sells admission tickets for \$9.00 on Thursday nights. At capacity, the theater holds 100 customers. The function M(n)=9n represents the amount of money the theater takes in on Thursday nights, where n is the number of customers. What is the domain of M(n) in this context?
A. all whole numbers
B. all non-negative rational numbers
C. all non-negative integers that are multiples of 9
D. all non-negative integers less than or equal to 100
