Okok.
Diketahui (f o g)(x) = 2x + 4 dan f(x) =x – 2. Tentukan fungsi g (x)!

Pake cara. ​

》Fungsi Komposisi

f(x) = x - 2

(fog)(x) = 2x + 4

(fog)(x) = f(g(x))

f(g(x)) = 2x + 4

g(x) - 2 = 2x + 4

g(x) = 2x + 4 + 2

g(x) = 2x + 6

#CMIIW

Nilai g(x)

(f o g)(x) = 2x + 4

f(g(x)) = 2x + 4

g(x) - 2 = 2x + 4

g(x) = 2x + 4 + 2

g(x) = 2x + 6

Pembuktian

(f o g)(x) = f(g(x))

= (2x + 6) - 2

= 2x + 6 - 2

= 2x + 4
