Diket: f(x)= 2x-1 , g(x) = 4-x Tentukan (f o g )-¹ (x)

- Invers Fungsi -

(fog)(x) = 2(4-x) -1
(fog)(x) = 8-2x-1
(fog)(x) = -2x+7
y = -2x+7
2x = 7-y
x = (7-y)/2
(fog)-¹(x) = (7-x)/2

semoga membantu
-vin

(fog)(x)=f[g(x)]
(fog)(x)=f(4-x)
(fog)(x)=2(4-x)-1
(fog)(x)=8-2x-1
(fog)(x)=7-2x
y=7-2x
2x=7-y
x=7-y/2

(fog)⁻¹(x)=7-x/2

Semoga Membantu
