Consider the function:
Actually, this record means the following chain of functional transformations:
that can be written by symbols of functional dependences in a general view as:
or more shortly:
We have here not the one rule of correspondence to transform x into y , but three consecutive rules (functions), using which we receive y from x . In this case we say that y is a composite function of x .
E x a m p l e . The following functions are composite ones:
Write, please, the two rest functions like this.
