फलन (f(x)=\frac{x-2-1}{x-1}) का ग्राफ \(x\ne1\) पर किस रेखा जैसा है?
For \(x\ne1\), the graph of (f(x)=\frac{x-2-1}{x-1}) is like which line?
Explanation opens after your attempt
Correct Answer
A. (y=x+1)
Concept
(\frac{x-2-1}{x-1}=\frac{(x-1)(x+1)}{x-1}=x+1), but (x=1) is excluded. Do not forget the hole in such graphs.
Why this answer is correct
The correct answer is A. (y=x+1). (\frac{x-2-1}{x-1}=\frac{(x-1)(x+1)}{x-1}=x+1), but (x=1) is excluded. Do not forget the hole in such graphs.
Exam Tip
(\frac{x-2-1}{x-1}=\frac{(x-1)(x+1)}{x-1}=x+1), लेकिन (x=1) हटता है। ऐसे ग्राफ में छेद को न भूलें।
