If \(f(x)=|x-1|+|x-2|\), then \(f^{\prime}(-2023)+\) \(\mathrm{f}^{\prime}\left(\frac{2024}{2023}\right)+\mathrm{f}^{\prime}(2023)=\)

  1. A \(1\)
  2. B \(-1\)
  3. C \(0\)
  4. D \(3\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(0\)

Step-by-step Solution

Detailed explanation

\begin{aligned} & \text { When } x=-2023 \Rightarrow f(x)=-(x-1)-(x-2)=-2 x+3 \\ & \Rightarrow f^{\prime}(x)=-2 \Rightarrow f^{\prime}(-2023)=-2 \\ & \text { When } x=\frac{2024}{2023} \Rightarrow f(x)=(x-1)-(x-2)=1 \\ & \Rightarrow f^{\prime}(x)=0 \Rightarrow…
