For this case we have a function of the form: [tex]y = A * (b) ^ t
[/tex] Where, A: initial amount b: growth rate t: time In this problem we have the following function: [tex]f (t) = 1000 (2.2) ^ t
[/tex] In this case, the growth rate is given by: [tex]b = 2.2
[/tex] Answer: the rate of increase is: b = 2.2
