    The domain of this function is first restricted to all nonnegative integers because the ferry can carry only a whole number number of cars.

    The domain is restricted to number less than or equal to 42 because the ferry cannot carry more cars than capacity.

    0 ≤ c ≤ 42

    Step-by-step explanation:

    The cost to take a car across a bay on a ferry is $16.

    The ferry has a capacity of 42 cars.

    Now, given that the revenue collected is a function of the number of cars, c.

    R (c) = 16c ... (1)

    As the maximum capacity of the ferry is 42 and the number of cars can not be negative but can be zero.

    So, the domain of the function (1) will be 0 ≤ c ≤ 42 (Answer)
