Question

A population of 40 foxes in a wildlife preserve quadruples in size every 13 years. The function y=40•4x​, where x is the number of 13​-year ​periods, models the population growth. How many foxes will there be after 26 ​years?

Answer 1

640

Explanation:

y = 40(4)^x

x = 26/13 = 2

y = 40(4)^2

y = 40 (16)

y = 640
