If you're looking for the simplified version of the fraction, you have to factor both numerator and denominator.
The numerator is actually already a prime number, so we're good
The denominator factors as 
So, a 3 appears in both numerator and denominator. We can simplify it:

If you want to compute the approximated value of this fraction, simply plug these values into some calculator to get

 
        
                    
             
        
        
        
Step-by-step explanation:
First, replace f(x) with y ⇒ f(x)=6x-19 ⇒ y=6x-19
Then y with x and x with y  ⇒ y=6x-19 ⇒ x=6y-19
Solve the equation from for y:
            x=6y-19
            x+19=6y dividing with 6
            1/6 x +(19/6) = y
Replace y with f−1(x) ⇒ f−1(x)= 1/6 x +(19/6)
hope this helps!

In order to get the answer to this question you will have to find the common factor and then divide the numerator and denominator by the common factor to get the answer.



 


Therefore the answer is "2."
Hope this helps.
