Respuesta :
The composition of the function and its inverse function is always one. Then the correct option is C.
What is the inverse of a function?
Suppose that the given function will be
f: X → Y
Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is
f⁻¹: Y → X
such that:
[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]
(and vice versa).
It simply means that the inverse of 'f' is a reverse operator, that takes back the effect of 'f'
Suppose that f and g are functions that are inverse of each other.
When f is composed of g or vice versa. Then the composition will be
We know that the composition of the function and its inverse function is always one. Then we get
When f is composed of g or vice versa. Then the composition will be 1.
Thus, the correct option is C.
