Diketahui        : f(x) = 2x - 12 dan g (x) = x - 10
Ditanya           : (f o g ) (x) ?
Penyelesaian : (f o g)(x) = f ( g(x) )
                                         = f (x-10)
                                         = 2 (x- 10) - 12
                                         = 2x - 20 - 12
                                         = 2x - 22
