फलन \(y=\frac{x^2-9}{x-3}\) में (x=3) पर ग्राफ में क्या दिखता है?
What appears in the graph of \(y=\frac{x^2-9}{x-3}\) at (x=3)?
Explanation opens after your attempt
A. छिद्रA hole
Concept
\(\frac{x^2-9}{x-3}=x+3\), but (x=3) remains excluded. Therefore the line-like graph has a hole.
Why this answer is correct
The correct answer is A. छिद्र / A hole. \(\frac{x^2-9}{x-3}=x+3\), but (x=3) remains excluded. Therefore the line-like graph has a hole.
Exam Tip
\(\frac{x^2-9}{x-3}=x+3\) है लेकिन (x=3) निषिद्ध रहता है। इसलिए रेखा जैसे ग्राफ में छिद्र होता है।
