Movie Galore Video Store is open every day of the year. To rent movies from the store, a person has to pay an annual membership fee of $20, plus $2.50 for each movie rented. To reduce the chance that movies are returned late, members are not allowed to rent more than 10 movies per day. Billy decides to become a member of the video store. Let x represent the number of movies that Billy could rent next year, and let f (x) represent the amount (in dollars) that he would pay the store as a result. Then f (x) is a function of x. What is the domain D and range R of f (x)?
