फलन (f(x)=\operatorname{sgn}(2-x)) में (x>2) होने पर मान क्या होगा?
For (f(x)=\operatorname{sgn}(2-x)), what is the value when (x>2)?
Explanation opens after your attempt
A. (-1)
Concept
If (x>2), then (2-x<0). Hence (\operatorname{sgn}(2-x)=-1).
Why this answer is correct
The correct answer is A. (-1). If (x>2), then (2-x<0). Hence (\operatorname{sgn}(2-x)=-1).
Exam Tip
यदि (x>2), तो (2-x<0)। इसलिए (\operatorname{sgn}(2-x)=-1) है।
