Answer: 5/4
Explanation: 
We have the same denominator so we can just add the numerator.
= 6/8 + 4/8 
=10/8
10/8 can be simplified 
=5/4
        
             
        
        
        
F(x) = 1 / (x - 2)...when x = 4
f(4) = 1 / (4 - 2)
f(4) = 1/2 <==
f(x) = 1 / (x - 2)...when f(x) = 1
1 = 1 / (x - 2) ...multiply both sides by (x - 2) eliminating it on the right
1(x - 2) = 1
x - 2 = 1
x = 1 + 2
x = 3 <==
