  1. A \(3 \pm \frac{\sqrt{2}}{3}\)
  2. B \(2 \pm \frac{2 \sqrt{3}}{3}\)
  3. C \(2 \pm \frac{\sqrt{3}}{2}\)
  4. D \(3 \pm \frac{\sqrt{3}}{3}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(2 \pm \frac{2 \sqrt{3}}{3}\)

Step-by-step Solution

Detailed explanation

We have, \[ \begin{aligned} & f(x)=(x-1)(x-2)(x-3) \\ & f(x)=x^3-6 x^2+11 x-6 \end{aligned} \] Given function is algebraic function so. it is continuous and difference in \([0,4]\) Now,…
