The following formulas give animal populations as functions of time,r. in years. Describe the growth of each population in words. (a) P = 1300 + 100/ The population is Its initial value is The change is happening at i (b) P = 2700-501 The population is Its initial value is The change is happening at (c) P = 1600 (1.06)' The population is Its initial value is The change is happening at (d) P = 500 -0.03 The population is Its initial value is 1 The change is happening at (e) P = 220 sin The population is 1 + 3500 () Its initial value is The change is happening at of > > > 1
