Misalkan ( f  g )(x ) = y
y
= . . . . .
x
= . . . . .
Jadi ( f  ) g  1 (x ) = . . . . .

c. ( f  f  1 )(x ) = . . . . .
= . . . . .

= . . . . .
= . . . . .
Jadi ( f  f  1 )(x ) = . . . . .

d. (g  1  f  1 )(x ) = . . . . .

= . . . . .
= . . . . .
= . . . . .
= . . . . .

e. ( f  ) g  1  ( f  g )(x ) = . . . . .
= . . . . .
= . . . . .

= . . . . .
= . . . . .
Jadi, ( f  ) g  1  ( f  g )(x ) = . . . . .
