What is the range of (f(x)=\sqrt{x}+3)?फलन (f(x)=\sqrt{x}+3) की रेंज क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ([3,\infty))([3,\infty))
Since (\sqrt{x} \ge 0), (\sqrt{x}+3 \ge 3). In exams adding (3) shifts the minimum value to (3).क्योंकि (\sqrt{x} \ge 0) इसलिए (\sqrt{x}+3 \ge 3)। परीक्षा में ऊपर (3) जोड़ने से न्यूनतम वैल्यू (3) हो जाती है।
