diketahui fungsi f : R R dan g R R di tentukan oleh f (x) =3x+4 dan g (x) = 6-2x tentukan (gof) -1 (x)

(gof)(x) = 6 - 2(3x + 4)
(gof)(x) = 6 - 6x - 8
(gof)(x) = -6x - 2
y = -6x - 2
6x = -2 - y
x = (-2 - y)/6
(gof)^-1(x) = (-2 - x)/6

(gof) (x) = g(3x + 4)
(gof) (x) = 6 - 2(3x + 4)
(gof) (x) = 6 - 6x - 8
(gof) (x) = -2 - 6x = y
-6x = y + 2
x = -1/6 (y + 2)

(gof)⁻¹ (x) = -1/6 (x + 2)
