What is the real domain of (f(x)=\frac{x+2}{x-1})?फलन (f(x)=\frac{x+2}{x-1}) का वास्तविक प्रान्त क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (R-{1})(R-{1})
Step 1: The denominator (x-1) must not be zero. Step 2: (x-1=0) gives (x=1). Step 3: So the domain is all real numbers except (1).चरण 1: हर (x-1) शून्य नहीं होना चाहिए। चरण 2: (x-1=0) से (x=1) मिलता है। चरण 3: इसलिए (1) को हटाकर सभी वास्तविक संख्याएँ प्रान्त हैं।
