Domain and range are terms that refer to the maximum and minimum variables along the x and y axis of a coordinate graph. Domain is looking at the x axis (independent variable). Range is looking at the y axis (dependent variable). In this situation, the amount of money James earns depends on how many hours he tutors after school each day. So, our situation would look like the following:
Domain = Independent Variable = The number of hours James spends tutoring.
Range = Dependent Variable = The total amount of money James earns tutoring.
