If (f(x)=\frac{x-2}{x+2}), which value will not be in the range of (f)?यदि (f(x)=\frac{x-2}{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-2}{x+2}). Step 2: From (y(x+2)=x-2), we get (x(y-1)=-2-2y). Step 3: Putting (y=1) leads to an impossible statement, so (1) is not in the range.चरण 1: (y=\frac{x-2}{x+2}) लिखें। चरण 2: (y(x+2)=x-2) से (x(y-1)=-2-2y) मिलता है। चरण 3: (y=1) रखने पर असंभव स्थिति बनती है, इसलिए (1) परास में नहीं है।
