If (f:\mathbb{R}\to\mathbb{R}) and (f(x)=|x|), which pair shows that (f) is not one-one?यदि (f:\mathbb{R}\to\mathbb{R}) और (f(x)=|x|), तो कौन-सा युग्म (f) को एकैकी न होना दिखाता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (2) and (-2)(2) और (-2)
Step 1: Absolute value can give the same output for positive and negative inputs. Step 2: (f(2)=2) and (f(-2)=2), while (2\ne -2). Step 3: In one-one tests, search for two different inputs with equal outputs.चरण 1: निरपेक्ष मान धन और ऋण दोनों को समान मान दे सकता है। चरण 2: (f(2)=2) और (f(-2)=2), जबकि (2\ne -2)। चरण 3: एकैकी जाँच में ऐसे दो अलग आगत खोजें जिनका निर्गत समान हो।
