CEVAP:

There are many ways of constructing new functions from the given ones. The most important way of constructing a new function from the known ones is the composition of them. We now give the definition of composition. Let the functions f : A›B and g : B›C be given.
The function g°f : A›C, defined by the rule (g°f )(a)=g(f (a)) is called the composition of the functions f and g.
