Consider a function that describes how a particular car gas mileage depends on its speed. What would appropriate domain for this function? A. 0 to 100 per hour
B. 0 to 50 miles per gallon
C. Times from 0 to 10 minutes
D. Times from -10 to 10 minutes

 A. 0 to 100 per hour

Explanation:

The phrasing "Depends on its speed" tells us that the speed is the independent variable, and therefore it's the x variable.

The domain is the set of allowed x values of a function, or allowed inputs. In this case, it appears the car's max speed is 100 mph.

Step-by-step explanation:

x<11

(-∞, 11)
