F(x)= xkuadrat2-3x dan g(x)=x+2. Fungsi (f°g)(x)?

Kelas 10 Matematika
Bab Fungsi Komposisi

(fog) (x) = f(x + 2)
(fog) (x) = (x + 2)² - 3 (x + 2)
(fog) (x) = x² + 4x + 4 - 3x - 6
(fog) (x) = x² + x - 2

Bab Komposisi Fungsi

F(x)= x^2-3x
g(x)=x+2

(fog)(x) = (x+2)^2 - 3(x+2)
= x^2 + 4x + 4 - 3x - 6
= x^2 + x - 2
