WebTo find the inverse of f we follow the following steps: Step 1 : Put f (x) = y, where y ∈ B and x ∈ A. Step 2 : Solve f (x) = y to obtain x in terms of y. Step 3 : In the relation obtained in step 2 replace x by f − 1 ( y) to obtain the required inverse of f. Example : Let f : R → R be defined by f (x) = ( e x – e − x) /2. WebA function f : X → Y is defined to be invertible if there exists a function g : Y → X such that gof = I X and fog = I Y. The function g is called the inverse of f and is denoted by f –1. An important note is that, if f is invertible, then f must be one-one and onto and conversely, if f is one-one and onto, then f must be invertible.
