If (f(x)=\sqrt{x}) and (g(x)=x+1), what is the real domain of ((f+g)(x))?यदि (f(x)=\sqrt{x}) और (g(x)=x+1) हों, तो ((f+g)(x)) का वास्तविक डोमेन क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ([0,\infty))([0,\infty))
For (\sqrt{x}), we need (x\ge 0), while (x+1) is defined for all real (x). Hence the domain is ([0,\infty)).(\sqrt{x}) के लिए (x\ge 0) चाहिए और (x+1) सभी वास्तविक (x) पर परिभाषित है। अतः डोमेन ([0,\infty)) है।
