If (f(x)=x^2-1) and (g(x)=x^2+1), what is the domain of (\frac{f}{g})?यदि (f(x)=x^2-1) और (g(x)=x^2+1) हैं, तो (\frac{f}{g}) का डोमेन क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( \mathbb{R} )( \mathbb{R} )
The denominator (x^2+1) is never (0), so no real number is excluded. Only real zeros of the denominator are removed.हर (x^2+1) कभी (0) नहीं होता, इसलिए कोई वास्तविक संख्या हटेगी नहीं। हर को शून्य बनाने वाली वास्तविक संख्या ही हटाई जाती है।
