Bab : Fungsi komposisi
=============================

f(x) = 3x - 2

g(x) = x² + 2


Maka,

(f o g) (x) = f(x² + 2)

(f o g) (x) = 3(x² + 2) - 2

(f o g) (x) = 3x² + 6 - 2

(f o g) (x) = 3x² + 4 ✔

(f o g) (x) = f(x² + 2)

(f o g) (x) = 3(x² + 2) - 2

(f o g) (x) = 3x² + 6 - 2

(f o g) (x) = 3x² + 4
