If f(x) = x-1/3 and g(x) = 3x+1 what is (fog)(x)
marin [14]

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
