If the function \( f(x) \) satisfies \( \lim _{x \rightarrow 1} \frac{f(x)-2}{x^{2}-1}=\pi \) then \( \lim _{x \rightarrow 1} f(x)= \)
- A \( 02 \)
- B \( 03 \)
- C \( 11 \)
- D \( 00 \)
Answer & Solution
Correct Answer
(A) \( 02 \)
Step-by-step Solution
Detailed explanation
Given that, \( \lim _{x \rightarrow 1} \frac{f(x)-2}{x^{2}-1}=\pi \rightarrow(1) \)
Clearly, if \( \lim _{x \rightarrow 1} f(x)=1 \) or \( 0 \) or \( 3 \). Then \( \lim _{x \rightarrow 1} \frac{f(x-2)}{x^{2}-1} \) doesn't exist, that is, contradicting Eq. (1).
Hence, option (1) is the correct answer.
