A saguaro cactus has a very slow growth rate. A study is being completed to determine if the growth rate of the cactus varies by age. The growth of a particular saguaro cactus can be
modeled by the function
h = f(t) = 0.779t + 10
where h is the height of the cactus in feet, and t is the time in years since the study began.
Part a)
Evaluate f^-(25) and interpret the result in the context of the problem.
Part b)
Find f^-1(h).
Part c)
In the context of the problem, describe how the function for Part b) might be used.
