Question

The function f(x) = 5,000(0.972)X, where x is the time in years, models a declining

lemming population. Approximately how many lemmings will there be in 4 years?
(Round your answer to the nearest whole number, and enter the number only.)

Answer 1

19440

Explanation:

f(x) = 5000(0.972)x

[x = time in years; therefore, substitute x with the given value]

["... how many lemmings will there be in 4 years?]

f(x) = 5000(0.972)4

f(x) = 19440
