Answer:
Option 3 - f(x)= 4x, 
Step-by-step explanation:
To find : Which two functions are inverses of each other?
Solution :
Two functions are inverse if 
Now, we find one by one
1) f(x)= x, g(x) = -x

Not true.
2) f(x)= 2x, 

Not true.
3) f(x)= 4x, 


i.e.
is true.
So, These two functions are inverse of each other.
4) f(x)= -8x, 

Not true.
Therefore, Option 3 is correct.
Answer:
The 3rd one is the correct answer.
