Understanding Inverse Functions: Properties and Notation Explained

Two functions f and g are inverses if they satisfy:

f(g(x)) = x and g(f(x)) = x

If two functions f and g are inverses, then the following properties hold true:

1. The composition of f with g results in the identity function.

2. The composition of g with f results in the identity function.

Formally, if f and g are inverses, then:

1. f(g(x)) = x for all x in the domain of g.
This means that after applying g to x, applying f will take you back to x.

2. g(f(x)) = x for all x in the domain of f.
This means that after applying f to x, applying g will take you back to x.

The inverse of a function f can be denoted as f^(-1) and is defined as the function that satisfies the above two properties. Note that not all functions have inverses. A function must be both one-to-one and onto in order to have an inverse.
