c is the number of customers and f(c) is the time it takes to clean up.

Because c is a positive whole number, this means 2c is also a positive whole number. Specifically 2c is a positive even whole number.

The range is the set of positive even integers. This is the possible set of times it takes to clean up for all possible inputs.
