If \(f:\mathbb{R}\to\mathbb{R}\), \(f(x)=2x^2+3x+1\), then (f) is not one-one. Which pair is correct?यदि \(f:\mathbb{R}\to\mathbb{R}\), \(f(x)=2x^2+3x+1\), तो (f) एकैकी नहीं है। कौन-सा युग्म सही है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (0) and \(-\frac{3}{2}\)(0) और \(-\frac{3}{2}\)
Step 1: Substitute two different values to find equal outputs. Step 2: \(f(0)=1\) and \(f\left(-\frac{3}{2}\right)=1\), while the inputs are different. Step 3: A quadratic function is not one-one on the entire real domain.चरण 1: दो अलग मान रखकर समान निर्गत खोजें। चरण 2: \(f(0)=1\) और \(f\left(-\frac{3}{2}\right)=1\), जबकि दोनों आगत अलग हैं। चरण 3: द्विघात फलन पूरे वास्तविक क्षेत्र पर एकैकी नहीं होता।
