If (f(x)=\frac{2x-3}{x+4}), why is (x=-4) excluded from the domain?यदि (f(x)=\frac{2x-3}{x+4}), तो (x=-4) को प्रांत से क्यों हटाया जाता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Because the denominator becomes zeroक्योंकि हर शून्य हो जाता है
Step 1: In a rational function, the denominator cannot be zero. Step 2: Substituting (x=-4) gives (x+4=0). Step 3: Hence (x=-4) is not included in the domain.चरण 1: भिन्न वाले फलन में हर शून्य नहीं हो सकता। चरण 2: (x=-4) रखने पर (x+4=0) हो जाता है। चरण 3: इसलिए (x=-4) प्रांत का भाग नहीं होगा।
