Answer 1

3514 1404 393

Answer:

A. non-negative integers ≤ 200

Explanation:

The number of passengers is a whole number (non-negative integer) that does not exceed 200. These are the values for which the function is defined.

The domain is non-negative integers less than or equal to 200.

You cannot have negative or fractional passengers, but you can have zero passengers. For 114 or more passengers, the airline will make a profit. There is no requirement for the profit to be positive.
