Answer:
Identity function
Step-by-step explanation:
We are given the following in the question:
Let f(x) be a function.
Then, inverse of f(x) can be written as:
[tex]f^{-1}(x)[/tex]
The composition function of the function and the reverse function can be found as:
[tex](f\circf^{-1})(x) = f(f^{-1})(x) = x[/tex]
which is an identity function.
Thus, the correct answer is
The identity function, f(x) = x, is formed by the composition of a function and its inverse.
