If (f(x)=x^2) and (g(x)=\sqrt{x}), what is the domain of ((f+g)(x))?यदि (f(x)=x^2) और (g(x)=\sqrt{x}) हैं, तो ((f+g)(x)) का प्रांत क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x \geq 0)(x \geq 0)
(x^2) is defined for all real (x), but (\sqrt{x}) needs (x \geq 0). The domain of the sum is the intersection.(x^2) सभी वास्तविक (x) के लिए परिभाषित है, लेकिन (\sqrt{x}) के लिए (x \geq 0) चाहिए। योग का प्रांत प्रतिच्छेद है।
