We have discussed the construction of new functions from existing functions using algebraic operations and composition of functions. Another tool for building new functions from known functions is the inverse function.
An inverse relation is the inverse of a given relation obtained by Interchanging or swapping the elements of each ordered pair. In other words, if (x, y) is a point in a relation R, then (y, x) is an element in the inverse relation R–1.
Inverse image $ f^{-1} ([n_0..n_1]) $ is the interesting one. Example of how this works is simply by choosing $f = \sqrt{x^2+y^2}$ and $g=([0..5]\mapsto 1)$ to get a (filled) circle with radius 5 from inverse image, distance function f, and simple range function g.
The inverse function is a function obtained by reversing the given function. The domain and range of the given function are changed as the range and domain of the inverse function. Let us learn more about inverse function and the steps to find the inverse function.

17 Αυγ 2024 · We examine how to find an inverse function and study the relationship between the graph of a function and the graph of its inverse. Then we apply these ideas to define and discuss properties of the inverse trigonometric functions.
Inverse Functions. Part 1. What is an Inverse Function? Let f be a 1 − 1 function with domain A and range B. Then, its inverse function , denoted by f − 1, has domain B and range A and is defined by: f − 1(y) = x ⇔ f(x) = y for any y ∈ B.
