Principle objective of this article is to Define and Discuss on Inverse Functions. Here discuss Inverse Functions with mathematical explanation. The inverse function for f (x), described f−1 (x) (which will be read “ f inverse of x”), contains the same area and range elements as the original function, f(x). However, the sets are switched. In other words, the domain of f (x) will be the range of f −1( x), as well as vice versa. In actuality, for every ordered set (a, b) belonging to f (x), there is often a corresponding ordered pair (b, a) that belongs to be able to f −1(x).
