If (f(x)=\sqrt{x-2}) and (g(x)=\sqrt{5-x}) then what is the domain of ((f+g)(x))?यदि (f(x)=\sqrt{x-2}) और (g(x)=\sqrt{5-x}) हैं तो ((f+g)(x)) का प्रांत क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \([2,5])\([2,5])
For square roots we need (x-2\ge 0) and (5-x\ge 0) so (2\le x\le 5). In such questions apply both conditions together.वर्गमूल के लिए (x-2\ge 0) और (5-x\ge 0) चाहिए इसलिए (2\le x\le 5)। ऐसे प्रश्नों में दोनों शर्तें साथ लगाएँ।
