Joanne drives a tour bus in Hollywood that can hold up to 10 passengers. She charges each passenger $15 dollars to ride. What is a reasonable domain for this scenario (see graph at right)?

A reasonable domain for this scenario would be a set of inputs that make sense within the context of the problem. In this case, the number of passengers that Joanne can accommodate in her tour bus is up to 10. So, a reasonable domain for this scenario would be the set of whole numbers from 0 to 10, inclusive.

Part of a line is graphed. Which inequalities could describe the domain and range?

The graph now shows the distance vs. time relationship for a race with a hare, a tortoise and a fox.

Which animal shows an increasing graph the entire race?
