The Sine Function The average number of customers per day at a home improvement store is given in the following table. Let x represent the day where 1 = Sun of the first week, 7 = Sat of the first week, 8 = Sun of the second week, and 14 = Sat of the second week.
Use a graphing calculator to produce a sine regression model for the data. Round a, b, c, and d to the nearest thousandth.

a. 33.690 sin(0.887 x + 1.337) + 81.684
b. 34.081 sin(0.888 x - 1.341) + 82.822
c. 34.081 sin(0.888 x - 1.341) + 82.8222
d. 33.690 sin( 0.887 x + 1.337) - 81.684
