1. Find the particular solution ofthe differential equation 2: = (x + 1)(x + 2) ify = % when x = -3. dzy 2. Find the particular solution of the differential equation E = 4(1 + 3902 ify = 1,y' = 2 when x = 1. 3. During 18 weeks from November 2009 to February 2010, the rate at which the number of cases of swine flu changed could be approximated by I'(t) = -6.34-t + 141.6, where I is the total number of people who have contracted swine flu and t is time measured in weeks. Estimate [(t), the total number who have contracted influenza by time t. Assume that 1(0) = 1408
