Web02. jan 2024. · This use of “–1” is reserved to denote inverse functions. To denote the reciprocal of a function f(x), we would need to write: (f(x)) − 1 = 1 f(x). An important relationship between inverse functions is that they “undo” each other. If f − 1 is the inverse of a function f, then f is the inverse of the function f − 1. WebWhy does a 'many to one' function not have an inverse? Because its hypothetical inverse would be 'one to many' which is not a function. This is because a single x-value would …

Inverse functions, in the most general sense, are functions that "reverse" each other. For example, if f f takes a a to b b, then the inverse, f^ {-1} f −1, must take b b to a a. Or in other words, f (a)=b \iff f^ {-1} (b)=a ...
