If (f={(a,1),(b,1),(c,2)}), which statement is correct?यदि (f={(a,1),(b,1),(c,2)}) है, तो कौन सा कथन सही है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: It is a function and it can be many-oneयह फलन है और यह अनेक-से-एक हो सकता है
Different first elements may have the same image, so a many-one function is valid. The common mistake is treating the same image as an error.अलग प्रथम अवयवों की समान छवि हो सकती है, इसलिए अनेक-से-एक फलन मान्य है। गलती यह है कि समान छवि को दोष मान लिया जाता है।
