Supponiamo che due variabili x e y siano inversamente proporzionali; allora possiamo rappresentarli come x ∝ 1 / y. Ciò significa che se il valore di x aumenta, il valore di y diminuisce e viceversa.
Suppose two variables x and y are inversely proportional; then we can represent them as x ∝ 1/y. That means, if the value of x increases, then the value of y decreases and vice versa.
        
             
        
        
        
Answer:
if you meant  f(x) = (x - 1) /3    then   f (g(x) ) = x
of if you meant  f(x) = x - (1/3) then  f(g (x)) =   3x + 2/3
Step-by-step explanation:
 f(x) = x-1/3 and g(x) = 3x+1 what is (fog)(x)
f ( g(x) ) =  (3x + 1)  - (1/3) =   3x  + 2/3
Or 
if you meant  f(x) = (x - 1) /3    then   f (g(x) ) = x
of if you meant  f(x) = x - (1/3) then  f(g (x)) =   3x + 2/3
