Question

A function is created to represent the miles per gallon your car gets. What

restrictions would be made to the domain? (1 point)

The domain would only include integers.

The domain would only include positive integers.

The domain would include all real numbers.

The domain would only include positive numbers.

Answer 1

The domain would only include positive numbers.

Step-by-step explanation:

The domain of a function represents the set of all possible input values for which the function is defined. In this case, the function represents the miles per gallon your car gets, which is a ratio of distance (miles) to fuel consumption (gallons).

Since distance and fuel consumption can both be expressed as positive real numbers, the domain of the function should include only positive real numbers. Integers and positive integers are too restrictive for the domain since it is possible to get non-integer values for miles per gallon, such as 24.5 miles per gallon. Therefore, the correct answer is that the domain would only include positive numbers.
