Description: Given a function f(x), its inverse f^(-1)(x) is defined by f(f^(-1)(x))=f^(-1)(f(x))=x. (1) Therefore, f(x) and f^(-1)(x) are reflections about the line y=x. In the Wolfram Language, inverse functions are represented using InverseFunction[f]. As noted by Feynman (1997), the notation f^(-1)x is unfortunate because it conflicts with the common interpretation of a superscripted quantity as indicating a power, i.e., f^(-1)x=(1/f)x=x/f. It is therefore important to keep in mind that the...
