IMPLICIT AND INVERSE FUNCTION THEOREMS φy(x2) = x2, then we have ∥x1 x2∥ 1 2 ∥x1 x2∥, which is only possible if x1 = x2. 1 Thus for each y 2 f(U), there is exactly one x such that f(x) = y.That is, f is one-to-one on U.This proves the first part of the theorem and that f 1 exists. We now show that f 1 is continuously differentiable with the stated derivative. Let y,y +k 2 V = f(U).

There may not be a single function whose graph can represent the entire relation, but there may be such a function on a restriction of the domain of the relation. The implicit function theorem gives a sufficient condition to ensure that there is such a The Implicit Function Theorem for R2. Consider a continuously di erentiable function F : R2!R and a point (x 0;y 0) 2R2 so that F(x 0;y 0) = c. If @F @y (x 0;y 0) 6= 0, then there is a neighborhood of (x 0;y 0) so that whenever x is su ciently close to x 0 there is a unique y so that F(x;y) = c. Moreover, this assignment is makes y a continuous function of x. 1 Why the Implicit Function Theorem is a great theorem In order to get information about the equation F ( x, y) = 0, (which we can think of as a system of k equation for y = ( The equation only tells us about solvability of the system for values of x close to a, with y close to b.

Implicit Function Theorems and Lagrange Multipliers 14.1. The Implicit Function Theorem for a Single Equation Suppose we are given a relation in 1R 2 of the form F(x, y) = O. (14.1) Then to each value of x there may correspond one or more values of y which satisfy (14.1)-or there may be no values of y which do so. If

The implicit function theorem guarantees that the first-order conditions of the optimization define an implicit function for each element of the optimal vector x* of the choice vector x. When profit is being maximized, typically the resulting implicit functions are the labor demand function and the supply functions of various goods.
