UCSS Math II 2.4.1 Example 3

A number of bacteria, [math]f(t)[/math], at any time [math]t[/math], in hours, can be estimated using the function [math]f(t) = 3000(1.24)^t[/math]. What was the initial size of the bacteria colony? Is the bacteria population exponentially decaying or growing?

[list=1] [*]Identify the value of the dependent quantity at [math]t = 0[/math]. [*]Identify the hourly rate of change in the function. [*]Describe how the rate of change relates to the change of the dependent quantity.
