Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: If (f(a)=f(b)), then (a=b)यदि (f(a)=f(b)) तो (a=b)
Step 1: In a one-one function, different inputs cannot give the same image. Step 2: Its algebraic form is (f(a)=f(b)\Rightarrow a=b). Step 3: Remembering the definition helps solve many questions quickly.चरण 1: एकैकी फलन में अलग-अलग आगत एक ही छवि नहीं दे सकते। चरण 2: इसका बीजगणितीय रूप है (f(a)=f(b)\Rightarrow a=b)। चरण 3: परिभाषा याद रखने से कई प्रश्न जल्दी हल हो जाते हैं।
