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