What is the real domain of (f(x)=\sqrt{x})?फलन (f(x)=\sqrt{x}) का वास्तविक प्रान्त क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ([0,\infty))([0,\infty))
Step 1: For a real square root, the expression inside must be non-negative. Step 2: Therefore (x\ge 0). Step 3: Hence the domain is ([0,\infty)).चरण 1: वास्तविक वर्गमूल के लिए अंदर की संख्या ऋणात्मक नहीं होनी चाहिए। चरण 2: इसलिए (x\ge 0) होना चाहिए। चरण 3: अतः प्रान्त ([0,\infty)) है।
