(D) Given $y = \frac{2x - 1}{x - 2}$ where $x 
eq 2$. To find the inverse,we solve for $x$ in terms of $y$: $y(x - 2) = 2x - 1$ $xy - 2y = 2x - 1$ $xy - 2x = 2y - 1$ $x(y - 2) = 2y - 1$ $x = \frac{2y - 1}{y - 2}$. Since the form of the inverse function $f^{-1}(y) = \frac{2y - 1}{y - 2}$ is identical to $f(x)$,the function is its own inverse. Now,differentiating $y$ with respect to $x$: $y' = \frac{(x - 2)(2) - (2x - 1)(1)}{(x - 2)^2} = \frac{2x - 4 - 2x + 1}{(x - 2)^2} = \frac{-3}{(x - 2)^2}$. Since $(x - 2)^2 > 0$ for all $x 
eq 2$,$y' Since both $(A)$ and $(B)$ are correct,the correct option is $(D)$.

The function $y = \frac{2x - 1}{x - 2}$ $(x \neq 2)$:
