फलन (f(x)=\operatorname{sgn}(x-2)) के ग्राफ में छलांग किस (x) पर होगी?
At which (x) will the graph of (f(x)=\operatorname{sgn}(x-2)) have a jump?
Explanation opens after your attempt
A. (x=2)
Concept
A signum graph changes when the inside expression becomes zero. From (x-2=0), we get (x=2).
Why this answer is correct
The correct answer is A. (x=2). A signum graph changes when the inside expression becomes zero. From (x-2=0), we get (x=2).
Exam Tip
साइनम ग्राफ अंदर की अभिव्यक्ति शून्य होने पर बदलता है। (x-2=0) से (x=2) मिलता है।
