Answer:
Option: A is the correct answer.
The appropriate domain for the function is:
A. All non-negative integers
Explanation:
We know that a domain of a function is the set of all the value of the independent variable at which the function is defined.
Here x represents the number of cars sold and F(x) represents their net profits (in dollars)
As we know that the profit will be zero when none of the car will be sold and also the car will be sold as a whole.Also, the profit is calculated when some cars are sold.
Hence, the x-value will be the set of all the positive integers.
Hence, the correct answer is:
Option: A
