What is the domain of (f(x)=\frac{x+5}{x^2-x-20})?फलन (f(x)=\frac{x+5}{x^2-x-20}) का डोमेन क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\mathbb{R}\setminus{-4,5})(\mathbb{R}\setminus{-4,5})
The denominator (x^2-x-20=(x-5)(x+4)), so (x\ne5) and (x\ne-4). In exams factorize the denominator.हर (x^2-x-20=(x-5)(x+4)) है इसलिए (x\ne5) और (x\ne-4)। परीक्षा में denominator को गुणनखंड करें।
