An initial population of 7 chipmunks increases by 6% each year. if the function f(x) = abx 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

Step-by-step explanation:

Given : An initial population of 7 chipmunks increases by 6% each year.

To Find: which function could you use to find the population after 8 years?

Solution:

We are given that the function models this situation

Where a is the initial amount.

b = 1+r

r is the rate of change

x is number of years

Since we are given that initial population is 7

So, a = 7

We are also given that chipmunks increases by 6% each year.

So, r = 6%=0.06

So, b = 1+r = 1+0.06 = 1.06

Now we are supposed to find the function which can be used to find the population after 8 years

So, x =8

Substitute the values in the function:

Thus Option B is correct .

Hence the function which represents the population after 8 years is

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
