What is the (x)-value of the intersection of the graphs (y=\sqrt{x+1}) and (y=x-1)?ग्राफ (y=\sqrt{x+1}) और (y=x-1) के प्रतिच्छेद का (x)-मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x=3)(x=3)
In (\sqrt{x+1}=x-1), (x\ge1), and at (x=3) both sides are (2). In exams, the right side must be non-negative before squaring.(\sqrt{x+1}=x-1) में (x\ge1) और (x=3) रखने पर दोनों (2) हैं। परीक्षा में वर्ग करने से पहले दाईं ओर अनऋणात्मक होनी चाहिए।
