Mariulka [41]

Answer:

Option D F(x)=150(0.85)^{x}

Step-by-step explanation:

In this problem we have a exponential function of the form

F(x)=a(b)^{x}

where

F(x) -----> the rabbit population

x ----> the number of weeks

a is the initial value

b is the base

In this problem we have

a=150 rabbits

b=1-r

r=15%=15/100=0.15

so

b=1-0.15=0.85

substitute the values

F(x)=150(0.85)^{x}
