Answer: 
Step-by-step explanation:
By definition the domain of an inverse function 
is the range of f(x) and the range of the inverse function is equal to the domain of the principal function f(x).
If you have a function 
, then to find the inverse function, follow these steps:
1. Make 
2. Solve for the variable "x":
3. Exchange the variable "x" with the variable "y":
4. Exchange "y" with
. Then the inverse function is:
Now you can see its pretty simple, its 128 but the way i got it is first you double 8 which makes 16 right then double 16 and you can see you got 32 then double 32 which makes 64 so next what you have to do is double 64 Obiously so you just double those numbers to get 128....Get it?
Answer: 13/15
