#### Answer

The graph of the function w=37000+4200c is shown below. The domain is from 0 to 8 cars. We will use a discrete graph.

#### Work Step by Step

The graph of the function w=37000+4200c is a discrete graph because the tractor-tailer can hold a maximum of 8 cars and a minimum of 0 cars. You also need a discrete graph because you can only have whole numbers of cars as you can't have half a car. Furthermore, the domain is 0 to 8 cars because it is the minimum and maximum amount of cars it can carry respectively and thus the graph is limited in this respect.
