David has been tasked with tracking the number of bagels sold (y) at Freddy's
24-Hour Bagel Shop from 12:00 AM (X = 0) to 12:00 PM (x = 12). David
notices that from 12:00 AM to 4:59 AM 5 more bagels are sold each hour
than were sold during the previous hour and from 5:00 AM to 12:00 PM the
number of bagels sold is a function of half the square of the time (x) minus 5
times the time (x) plus 15. Which of the following graphs is representative of
David's findings?
