\(f(x)\) is an \(n^{\text {th }}\) degree polynomial satisfying \(f(x)=\frac{1}{2}\left|\begin{array}{cc}f(x) & f\left(\frac{1}{x}\right)-f(x) \\ 1 & f\left(\frac{1}{x}\right)\end{array}\right|\). If \(f(2)=33\), then the value of \(f(3)\) is
- A \(126\)
- B \(214\)
- C \(244\)
- D \(-124\)
Answer & Solution
Correct Answer
(C) \(244\)
Step-by-step Solution
Detailed explanation
\(f(x)=\frac{1}{2}\left(f(x)f\left(\frac{1}{x}\right) - \left(f\left(\frac{1}{x}\right)-f(x)\right)\right)\) \(2f(x) = f(x)f\left(\frac{1}{x}\right) - f\left(\frac{1}{x}\right) + f(x)\) \(f(x) = f\left(\frac{1}{x}\right)(f(x)-1)\) Let \(P(x) = f(x)-1\). Then \(f(x) = P(x)+1\).…
