फलन (f(x)=\frac{|x|}{x}) का (x<0) पर ग्राफ किस रेखा पर होता है?
For (f(x)=\frac{|x|}{x}), on which line does the graph lie for (x<0)?
Explanation opens after your attempt
Correct Answer
A. (y=-1)
Concept
When (x<0), (|x|=-x), so (f(x)=-1). In the sign function, (x=0) is excluded separately.
Why this answer is correct
The correct answer is A. (y=-1). When (x<0), (|x|=-x), so (f(x)=-1). In the sign function, (x=0) is excluded separately.
Exam Tip
जब (x<0), तब (|x|=-x), इसलिए (f(x)=-1)। चिन्ह फलन में (x=0) अलग से हटता है।
