F⁻¹(x) stands for the invers of function f(x). The inverse of f(x) is equal to x. We need to solve for x.
solve for x
f(x) = 2x + 2
2x + 2 = f(x)
2x = f(x) - 2
x =

f⁻¹(x) =

Determine the value of f⁻¹(x) when x = 4
f⁻¹(x) =

f⁻¹(4) =

f⁻¹(4) =

f⁻¹(4) = 1
When x = 4, the value of f⁻¹(x) is equal to 1
You need the total amount of how many animals
63 5 tens=50
13 ones=10 and 3 leftover 50+13=63
1 trillion can be written as 1,000,000,000,000
1 billion can be written as 1,000,000,000
There are 3 more 0’s in 1 trillion than there are in 1 billion, so therefore 1 trillion is 1,000 times greater than 1 billion.

So Colin is required to pay $300 for 15 total months in order to get his credit card balance down to $0.
In order to find this total, we need to take the amount he is going to pay per month ($300) and multiply is by the total number of months that he is going to be paying that amount (15):
$300 * 15 months = $4,500
The total amount of money that he is going to pay after his card balance reaches $0 is $4,500.
However, Colin only maxed out his credit card to $4,000 - the rest of the money is due to interest. So to find this amount, we take the total amount that he paid ($4,500) and subtract it from the total amount he initially maxed out his card with ($4,000):
$4,500 - $4,000 = $500
The amount of interest that Colin has paid when his credit card balance is $0 is $500.
