Mapel : MatematikaKelas : 10
Bab : Fungsi Komposisi
_____________________
(f o g) (x) = f(x + 2)
(f o g) (x) = 5(x + 2) + 3
(f o g) (x) = 5x + 13
Untuk Menentukan, invers fungsi (f o g) (x)
Misalkan:
_______
5x + 13 = y
5x = y - 13
x = (y - 13)/5
Sehingga, Fungsi invers (f o g) (x) adalah
(f o g) -¹(x) = (x - 13)/5
