1.	A function is said to be ______________ if and only if f(a) = f(b) implies that a = b for all a and b in the domain of f.(a) One-to-many(b) One-to-one(c) Many-to-many(d) Many-to-oneThis question was addressed to me by my school teacher while I was bunking the class.Query is from Functions in section Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics
Answer» CORRECT option is (B) One-to-one To EXPLAIN: A function is one-to-one if and only if f(a)≠f(b) WHENEVER a≠b.
