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

Langsung aja y

(gof)(x) = g{f(x)}

= 6 - 2f(x)
= 6 - 2(3x + 4)
= 6 - 6x - 8
= -6x - 2

(gof)(x) = -6x - 2
y = -6x - 2
6x = -y - 2
x = (-y - 2) / 6

(gof)`¹(x) = (-x - 2) / 6

Semoga berguna +_+

Bab Fungsi Komposisi
Matematika SMA Kelas X

(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)
