Grade 9 Functions and Relations CCSS: HSF-LE.B.5
Clinton recently started working at a small library and is responsible for returned books. Each day when he begins, there are some books already waiting by the return slot in the door. As the day progresses, more people return books. Clinton first thought that the function B(t)=15h+4 models the number of books returned during a day, where B is the total number of books returned on a single day, and h is the number of hours since the library opened. After a few more days, Clinton realizes he was wrong, and that books are returned more frequently during the day than he had originally estimated. Which of the following functions could be a possible alternative?
- B(h)=16h+3
- B(h)=15h+4+5t
- B(h)=15h+5
- B(h)=20h+4
