फलन (f(x)=\operatorname{sgn}(2x-8)) के ग्राफ में छलांग किस (x) पर होगी?
At which (x) will the graph of (f(x)=\operatorname{sgn}(2x-8)) have a jump?
Explanation opens after your attempt
A. (x=4)
Concept
A signum graph changes when the inside expression is zero. From (2x-8=0), we get (x=4).
Why this answer is correct
The correct answer is A. (x=4). A signum graph changes when the inside expression is zero. From (2x-8=0), we get (x=4).
Exam Tip
साइनम ग्राफ अंदर की अभिव्यक्ति शून्य होने पर बदलता है। (2x-8=0) से (x=4) मिलता है।
