Answer: 11 9/35
Step-by-step explanation: just add the whole number to the fraction.
 
        
                    
             
        
        
        
Let the function be represented by f(x).
Multiplying the number x by 4 results in 4x. Subtracting 2 from results give 4x - 2. So the function becomes:
f(x) = 4x - 2
Finding the inverse function:
Replace f(x) by y, and isolate x on one side of the equation and find the inverse:

Yes the inverse function represents the reverse process. Original function involved multiplication by 4 and then subtraction of 2. Inverse function involves addition of 2 and then division by 4. So the inverse represents the reverse of the given process. 
 
        
                    
             
        
        
        
Percent change = ((new value) - (old value))/(old value) × 100%
  = (3710 - 6000)/6000 × 100%
  = -38.16%
The decrease in circulation is about 38%.
