1.	For an inverse to exist it is necessary that a function should be __________(a) injection(b) bijection(c) surjection(d) none of the mentionedThe question was asked by my school principal while I was bunking the class.My question comes from Inverse of a Function in division Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics
Answer» Correct CHOICE is (B) bijection To explain: Inverse EXIST only for those functions which are ONE one and ONTO.
