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. Webg is the inverse of f. A function, f: A → B, is said to be invertible, if there exists a function, g : B → A, such that g o f = IA and f o g = IB. The function, g, is called the inverse of f, and is denoted by f -1.
