Kelas 10 Matematika
Bab Fungsi Komposisi

f(x + 2) = 2/x
f(x - 2 + 2) = 2/(x - 2)
f(x) = 2/(x - 2)
***************************************
(f⁻¹ o f⁻¹) (x) = (f o f)⁻¹

y = (ax + b)/(cx + d)
y⁻¹ (-dx + b)/(cx - a)

****************************************
(f o f) = f(f(x))
(f o f) = f(2/(x - 2))
(f o f) = 2/(2/(x - 2) - 2)
y = 2/(2 - 2 (x - 2))/(x - 2))
y = 2/((2 - 2x + 4)/(x - 2))
y = 2/((6 - 2x)/(x - 2))
y = 2 . (x - 2)/(6 - 2x)
y = 2 . (x - 2)/(2 . (3 - x))
y = (x - 2)/(- x + 3)
y⁻¹ = (-3x - 2)/(-x - 1)
(f o f)⁻¹ = (3x + 2)/(x + 1)
