Question

PLEASE HELP!!!

The number of users of the internet in a town increased by a factor of 1.01 every year from 2000 to 2010. The function below shows the number of internet users f(x) after x years from the year 2000.

f(x) = 3000(1.01)^x

Which of the following is a reasonable domain for the function?

0 ≤ x ≤ 10

2000 ≤ x ≤ 2010

0 ≤ x ≤ 3000

All positive integers

Answer 2

Any idea?

Answer 3

Domain will answer the question "What can x be?"

Answer 4

I have no clue

Answer 5

What can x be?

Answer 6

I don't know. I'm new to this type of math.

Answer 7

Well it's from the year 2000 to 2010

Answer 8

Conventionally we would set 2000 as the origin

Answer 9

So \(0\le x\le10\)

Answer 10

Oh. So would it be A or B?

Answer 11

Because what you wrote about the years 200-2010 and 0≤x≤10

Answer 12

sorry *2000

Answer 13

But you won't have \(\Large 3000\times1.01^{2000}\) because the index is too large

Answer 14

Oh. So it's A right? :)

Answer 15

Yep :)

Answer 16

THANKS :)

Answer 17

no problem :D
