dik: (gof) (x) = 11x-3 f (x) = 2x+3 dit: g (x) =..?

g(f(x)) = 11x-3
g(2x + 3) = 11x - 3
2(g(x))+ 3 = 11x - 3
g(x) = 11x -3-3/2
g(x) = 11x - 6/2
Maaf kalau kurang tepat

(gof) (x) = 11x - 3
g(2x + 3) = 11x - 3
g(2 . x/2 + 3) = 11 . (x/2) - 3
g(x + 3) = (11x/2) - 3
g(x - 3 + 3) = 11 (x - 3)/2 - 3
g(x) = (11x - 3 - 6)/2
g(x) = (11x - 9)/2
g(x) = (11/2) x - (9/2)
