Consider a function that describes how a particular car’s gas mileage depends on its speed. what would be an appropriate domain for this function? 0 to 100 miles per hour 0 to 50 miles per gallon times from 0 to 10 minutes times from –10 to 10 minutes

Domain: All x-values.

Note that x-values are independent values and often than not time. Therefore you could draw a line through ''0 to 50 miles per gallon''. From ''-10 to 10 minutes'' doesn't make any sense for a negative number shouldn't be included. The standard unit for speed is mph (or kph in other countries) which means miles per hour. Cross out ''0 to 10 minutes''.

The correct answer would be 0 to 100 mph.
