~~~~~~~~~~~~~~~~~~~~~

They want you write an exponential function of the form

    R(n) = ,

where R(n) is the population of rabbits "n" years from today, n = 0, 1, 2, 3, . . . 


It is

    R(n) =  = ,


Thus a = 500 is the starting (initial) population;  b = 1.25 is the base of the exponential function
(the yearly growth coefficient).


Aften 10 years, the population will be

    R(10) =  = use your calculator = 4656.612873 = 4657 (rounded).    ANSWER

Solved.
