If (f(x)=\frac{2x}{x-1}), does (f(x)=2) have a real solution?यदि (f(x)=\frac{2x}{x-1}), तो (f(x)=2) का कोई वास्तविक हल है या नहीं?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: No, it has no real solutionनहीं, कोई वास्तविक हल नहीं है
Step 1: Assume (\frac{2x}{x-1}=2). Step 2: This gives (2x=2x-2), which is impossible. Step 3: Therefore (2) is not in the range of this function.चरण 1: (\frac{2x}{x-1}=2) मानें। चरण 2: इससे (2x=2x-2) मिलता है, जो असंभव है। चरण 3: इसलिए (2) इस फलन के परास में नहीं आता।
