Question

An initial population of 7 chipmunks increases by 6% each year. If the function f(x) = ab^x models this situation, which function could you use to find the population after 8 years?

A) f(x) = 8(1.06)^7
B) f(x) = 7(1.06)^8
C) f(x) = 7(0.06)^8
D) f(x) = 8(0.06)^7

Answer 1

B) f(x) = 7(1.06)⁸

Explanation:

f(x) = ab^x

a = 7

b = (106/100) = 1.06
