Explanation opens after your attempt
Correct Answer
D. ( 2 )
Concept
For (1<x<4), (\operatorname{sgn}(x-1)=1) and (\operatorname{sgn}(x-4)=-1). In exams, check the sign of each signum term separately.
Why this answer is correct
The correct answer is D. ( 2 ). For (1<x<4), (\operatorname{sgn}(x-1)=1) and (\operatorname{sgn}(x-4)=-1). In exams, check the sign of each signum term separately.
Exam Tip
(1<x<4) पर (\operatorname{sgn}(x-1)=1) और (\operatorname{sgn}(x-4)=-1) है। परीक्षा में हर साइनम पद का चिह्न अलग जांचें।
