1.	The following figure represents which type of function?(a) one-one(b) onto(c) many-one(d) neither one-one nor ontoI had been asked this question by my college professor while I was bunking the class.My query is from Types of Functions topic in section Relations and Functions of Mathematics – Class 12
Answer» Right ANSWER is (b) ONTO The best explanation: The above FUNCTION is onto or surjective. A function f:X→Y is SAID to be surjective or onto if, every element of Y is the IMAGE of some elements in X. The condition for a surjective function is for every y∈Y, there is an element in X such that f(x)=y.
