Jawab:
g(x) = x - 1
Penjelasan dengan langkah-langkah:
(fog) (x) = x² - 2x + 6
f(g(x)) = x² - 2x + 6
(g(x))² + 5 = x² - 2x + 6
(g(x))² = x² - 2x + 6 - 5
(g(x))² = x² - 2x + 1
g(x) = √(x - 1)²

Bab 6 - Fungsi
f(x) = x² + 5
(f o g)(x) = x² - 2x + 6
g(x) = ?
(f o g)(x) = f(g(x))
x² - 2x + 6 = (g(x))² + 5
(g(x))² = (x - 1)²
Semoga Bermanfaat!
