An inverse function is a second function which undoes the work of the first one. In this unit we describe two methods for finding inverse functions, and we also explain that the domain of a function may need to be restricted before an inverse function can exist.
Inverse Relations and Functions. 11.1 OBJECTIVES. Find the inverse of a relation. Graph a relation and its inverse. Find the inverse of a function. Graph a function and its inverse. Identify a one-to-one function. Let’s consider an extension of the concepts of relations and functions discussed in Chapter 3. Suppose we are given the relation.
Let g : B ! A be a function. Then we say that g is the inverse of f, and denote it f 1, if g f = 1A and f g = 1B. For each function f, draw the arrow diagram of f. Draw the arrow diagram of f 1 or explain why f 1 doesn't exist. f : fA; B; Cg ! f1; 2; 3g given by f(A) = 1; f(B) = 3; f(A) = 2.
