Inverse Functions 2


The definition of inverse functions.

An inverse function, of a function , is a function such that for all x in the domain of and for all y in the target of . Informally we can think of undoing the work that has done. Therefore, when evaluating or , the original value, x, will be obtained. The graph below shows the functions , and the points A and B. By adjusting the values of a, you can move the points A and B.
