Under which condition will (f:\mathbb{R}\to\mathbb{R}), (f(x)=x^3+ax), certainly be one-one?फलन (f:\mathbb{R}\to\mathbb{R}), (f(x)=x^3+ax) किस शर्त पर निश्चित रूप से एकैकी होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (a>0)(a>0)
Step 1: When (a>0), both (x^3) and (ax) are increasing parts. Step 2: Their sum is also increasing, so different inputs give different images. Step 3: In parameter questions, carefully observe the sign of the coefficient.चरण 1: (a>0) होने पर (x^3) और (ax) दोनों बढ़ते हुए भाग हैं। चरण 2: उनका योग भी बढ़ता है, इसलिए अलग आगत अलग छवि देंगे। चरण 3: पैरामीटर वाले प्रश्नों में गुणांक का चिन्ह ध्यान से देखें।
