A local drive-in theatre sells entrance tickets for cars on weekend nights. At capacity, the drive-in can hold 73 cars. the function C(n)= 25n represents the drive-in's revenue on a weekend night, where n represents the number of cars. In this situation, what is the domain of C(n)?
The domain of C(n) is the set of all possible values of n for which the function is defined. In this case, the number of cars (n) cannot be negative because it doesn't make sense to have a negative number of cars. Additionally, the number of cars cannot exceed the maximum capacity of the drive-in, which is 73. Therefore, the domain of C(n) is the set of all non-negative integers less than or equal to 73:
Domain: {0, 1, 2, 3, ..., 73}
