Jika diketahui f(x)=x kuadrat g(x)=(x-1) Tentukan: a.(fog)(x) b.(gof)(x) Tolong di jawab

f(x) = x²
g(x) = (x - 1)

a. (fog)(x) = f(g(x))
                 = (x - 1)²
                 = x² - 2x + 1

b. (gof)(x) = (g(f(x))
                 = x² - 1

Fungsi Komposisi

f(x) = x²
g(x) = x - 1

(fog)(x) = (x - 1)² = x² - 2x + 1 ✔

(gof)(x) = x² - 1 ✔
