A ticket window at a theater opened at 9:00 a.m. and closed at 5:00 p.m. At the beginning of each hour, the number of people in line was recorded. The graph shows the number of people in lines as a function of the time, where = 0 represents 9:00 a.m. and 11= 8 represents 5:00 p.m. 50 40 Number of People in Line 35 30 25 20 15. 223 10 5 Time (hours from 9:00a.m.) The number of people in line at time can be modeled by the cubic function f) = -0.40 +5.4417 - 21.93 +44.26. At 11:00 a.m., approximately what was the difference between the number of people in line as recorded on the graph and the number in line as predicted by the model fit)?
