Wed Aug 15 2001 14:30:00 GMT-0400 (Eastern Daylight Time) · In mathematics an inverse function (or anti- function ) is a function that “reverses” another function : if the function f applied to an input x gives a result of y then applying its inverse function g to y gives the result x i.e. g(y) = x if and only if f(x) = y. The inverse function of f is also denoted as −.. As an example consider the real-valued function …

Wed Sep 18 2002 14:30:00 GMT-0400 (Eastern Daylight Time) · In mathematics the graph of a function f is the set of ordered pairs (x y) where f(x) = y.In the common case where x and f(x) are real numbers these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.. In the case of functions of two variables that is functions whose domain consists of pairs (x y) the graph …

In mathematics specifically differential calculus the inverse function theorem gives a sufficient condition for a function to be invertible in a neighborhood of a point in its domain: namely that its derivative is continuous and non-zero at the point.The theorem also gives a formula for the derivative of the inverse function .In multivariable calculus this theorem can be generalized to any …
