Question

on an island without squirrels some squirrels are introduced. a mathematical model of the population growth of squirrels on the island is given by the function f defined by

f(x)= 1320/(1 + e^(5,1-0.66x))

where x is the time in years after the introduction

a)how many squirrels were introduced in the island?
b) how many squirrels are living on the island after 6 years

Thanks a lot

Answer 1

a) 1320 squirrels because there are no variables next to it(it is a constant)

Answer 2

I am going to assume that you are using a comma instead of the North American period to indicated the decimal place, so I will read that as:

f(x)= 1320/(1 + e^(5.1 - 0.66x)) ,

(why are you using the comma in the first number and then the period in 0.66 ??)

so at introduction, x = 0
and
f(0) = 1320/( 1 + e^5.1) = appr 8

after 6 years,
f(6) = 1320/(1 + e^(5.1 - .66(6))
= ....

you do the button-pushing
