ग्राफ \(y=\sqrt{x}\) और (y=x-2) के प्रतिच्छेद का (x)-मान क्या है?
What is the (x)-value of the intersection of the graphs \(y=\sqrt{x}\) and (y=x-2)?
Explanation opens after your attempt
Correct Answer
C. (x=4)
Concept
In \(\sqrt{x}=x-2\), \(x\ge2\), and for (x=4) both sides are (2). In exams, check \(x-2\ge0\) before squaring.
Why this answer is correct
The correct answer is C. (x=4). In \(\sqrt{x}=x-2\), \(x\ge2\), and for (x=4) both sides are (2). In exams, check \(x-2\ge0\) before squaring.
Exam Tip
\(\sqrt{x}=x-2\) में \(x\ge2\) और (x=4) रखने पर दोनों (2) होते हैं। परीक्षा में वर्ग करने से पहले शर्त \(x-2\ge0\) देखें।
