If (f:\mathbb{R}\to\mathbb{R}), (f(x)=e^x+x), which statement about the one-one nature of (f) is correct?यदि (f:\mathbb{R}\to\mathbb{R}), (f(x)=e^x+x), तो (f) की एकैकीता के बारे में सही कथन कौन-सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: It is one-oneएकैकी है
Step 1: (e^x) is increasing and (x) is also increasing. Step 2: The sum of two increasing parts is increasing, so two different inputs cannot have the same image. Step 3: In such questions, quickly identify the increasing nature of the function.चरण 1: (e^x) बढ़ता है और (x) भी बढ़ता है। चरण 2: दो बढ़ते हुए भागों का योग भी बढ़ता है, इसलिए दो अलग आगत समान छवि नहीं देंगे। चरण 3: ऐसे प्रश्नों में फलन की बढ़ने की प्रकृति जल्दी पहचानें।
