D. The domain would only include positive numbers

Answer:

Option: D is the correct answer.

     D. The domain would only include positive numbers.

Step-by-step explanation:

Domain of a function--

It is the set of all the x-values or the values of the independent values for which the function is defined.

Here the function is used to represent the miles per gallon your car gets.

i.e. the independent variable is the number of gallons the car gets.

and the dependent variables is the number of miles covered by the car.

As the number of gallons of the car can't be negative or zero , it could be any positive number.

Hence, the domain would include any positive number.
