Question

The function f(x) 32(1.5) represents the chipmunk population of a forest x years after it was first studied. What was the original population of chipmunks?

A) 32

B) 21

C) 48

D) 72

Answer 1

A) 32

Explanation:

I will assume the function is

f(x) = 32 (1.5)^x

This is in the form

y =a b^x

in which a is the initial value, b is the growth rate, x is the time

a =32, which is the initial population

b= 1.5, which means 1.5-1 = .5. which means it grows at a 50% increase

x = number of years
