ग्राफ (y=\operatorname{sgn}(x+2)+\operatorname{sgn}(x-2)) का मान (x>2) पर क्या है?
What is the value of the graph (y=\operatorname{sgn}(x+2)+\operatorname{sgn}(x-2)) for (x>2)?
Explanation opens after your attempt
Correct Answer
D. (2)
Concept
For (x>2), both (x+2) and (x-2) are positive, so both signum values are (1). In exams, check the sign of each signum term separately.
Why this answer is correct
The correct answer is D. (2). For (x>2), both (x+2) and (x-2) are positive, so both signum values are (1). In exams, check the sign of each signum term separately.
Exam Tip
(x>2) पर दोनों (x+2) और (x-2) धनात्मक हैं इसलिए दोनों साइनम मान (1) हैं। परीक्षा में हर साइनम पद का चिह्न अलग जांचें।
