Question

plez explain composition of functions and invertible functions.....​

Answer 1

Step-by-step explanation:

In other words, if a function, f whose domain is in set A and image in set B is invertible if f-1 has its domain in B and image in A. f(x) = y ⇔ f-1 (y) = x. Not all functions have an inverse. For a function to have an inverse, each element b∈B must not have more than one a ∈ A.

Answer 2

Answer:

Composition of a function and its inverse function

(f∘f−1)(x)=(f−1∘f)(x)=x. If the domain or the range of f(x) is restricted, then the composition of the function and its inverse is also x, but only on an interval.
