Answer:
D
Step-by-step explanation:
When f(x) is equal to 0, x=4.
 
        
             
        
        
        
I think it's 2.2. I apologize if it's incorrect
        
                    
             
        
        
        
So we are given the expression:
 ÷
 ÷ 
When we divide fractions, we must flip the second term and change the sign to multiplication:

And then we multiply across:

Then we can break apart all of the like variables for simplification:

When we simplify variables through division, we subtract the exponent of the numerator from the exponent of the denominator. So we then have:



So then we multiply all of these simplified parts together:

So now we know that the simplified form of the initial expression is:  .
