Sometimes we will need to know an inverse function for all elements of its domain, not just a few. To learn how to determine if a function even has an inverse, read on!

In this section we explore the relationship between the derivative of a function and the derivative of its inverse. The calculator will find the inverse of the given function, with steps shown. Intro to Finding the Inverse of a Function Before you work on a find the inverse of a function examples, letâs quickly review some important information: Notation: The following notation is used to denote a function (left) and itâs inverse (right). If function f is not a one-to-one then it does not have an inverse. Or in other words, f ( a) = b f â 1 ( b) = a. f (a)=b \iff f^ {-1} (b)=a f (a) = b f â1(b) = a. f, left parenthesis, a, right parenthesis, equals, b, \Longleftrightarrow, f, start superscript, minus, 1, end superscript, left parenthesis, b, right parenthesis, equals, a. .
