Tolong dijawab pertanyaan dibawah Mau dibawa bsok ..

jawab

f(x)  = 3x + 2
g(x)= 3x^2 - x - 2

(f/g )x =  f(x) / g(x) =  (3x + 2)/ (3x^2 - x - 2) 
(f/g)(x) = (3x + 2) / (3x+2)(x - 1)
(f/g)(x) = 1/(x - 1)

(g/f)x = g(x) / f(x) = (3x^2 - x - 2)/(3x +2)
(g/f)(x) = (3x+2) ( x - 1)/ (3x +2)
(g/f)(x) = x - 1
