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
