Functions and Domain in Context

What are the domain and range for this relationship?

Which of the following are true:

• This is a function

• This is a continuous function

Joe had a summer job that pays $7.00 an hour and he worked at least 15 and no more than 35 hours every week. His weekly salary can be modeled by the equation: S = 7h, where S is his weekly salary and h is the number of hours he worked in a week. Describe the domain for this problem using appropriate notation.
