If we have a function f: A, B, there may exist an inverse function f-1: B→ A, which is defined by the rule f - (b) = a where b = (a). This definition only works if each b ≤ B an image point under f and if there is only ca point a such that of (a) = b. What do the functions or mappings are called? — PPSC Point
