फलन (y=|x-1|-|x+3|) का (x>1) के लिए मान क्या होगा?
For (x>1), what is the value of (y=|x-1|-|x+3|)?
Explanation opens after your attempt
A. (y=-4)
Concept
For (x>1), (|x-1|=x-1) and (|x+3|=x+3). Therefore (y=(x-1)-(x+3)=-4).
Why this answer is correct
The correct answer is A. (y=-4). For (x>1), (|x-1|=x-1) and (|x+3|=x+3). Therefore (y=(x-1)-(x+3)=-4).
Exam Tip
(x>1) पर (|x-1|=x-1) और (|x+3|=x+3) है। इसलिए (y=(x-1)-(x+3)=-4) मिलता है।
