Functions Solutions

Consider a function that describes how a particular car's gas mileage depends on its speed. What would an appropriate domain for this function be?
Choose the correct answer below.
(A) An appropriate domain would be 0 to 50 miles per gallon because the gas mileage is the independent variable of the function, and the domain consists of all reasonable values of the independent variable.
(B) An appropriate domain would be times from 0 to 10 minutes because the time is the dependent variable of the function, and the domain consists of all reasonable values of the dependent variable.
(C) An appropriate domain would be 0 to 50 miles per gallon because the gas mileage is the dependent variable of the function, and the domain consists of all reasonable values of the dependent variable.
(D) An appropriate domain would be 0 to 100 miles per hour because the speed is the dependent variable of the function, and the domain consists of all reasonable values of the dependent variable.
(E) An appropriate domain would be 0 to 100 miles per hour because the speed is the independent variable of the function, and the domain consists of all reasonable values of the independent variable.
