If (f(x)=\frac{x+1}{x-2}), which value will not be in the range of (f)?यदि (f(x)=\frac{x+1}{x-2}), तो कौन-सा मान (f) के परास में नहीं आएगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (1)(1)
Step 1: Write (y=\frac{x+1}{x-2}). Step 2: From (y(x-2)=x+1), we get (x(y-1)=2y+1). Step 3: Putting (y=1) gives an impossible statement, so (1) is not in the range.चरण 1: (y=\frac{x+1}{x-2}) लिखें। चरण 2: (y(x-2)=x+1) से (x(y-1)=2y+1) मिलता है। चरण 3: (y=1) रखने पर असंभव स्थिति बनती है, इसलिए (1) परास में नहीं है।
