jika f(x+1) = 3x-5 dan fog (x+2)=4x+8, tentukan fungsi g(x) lengkap dengan cara

Langsung aja y

Misal:
x+2 = a
x = a-2

(fog)(a) = 4(a-2) + 8
(fog)(a) = 4a - 8 + 8
(fog)(x) = 4x

Misal :
x+1 = a
x = a-1

f(a) = 3(a-1) - 5
f(a) = 3a - 3 - 5
f(x) = 3x - 8

(fog)(x) = f{g(x)}
4x = 3g(x) - 8
3g(x) = 4x + 8
g(x) =(4x + 8) / 3

Semoga berguna +_+
