It appears that the text extraction from the image wasn't successful. Let me instead interpret the equation manually:

The function shown in the image is:

$f(x) = \frac{x - 2}{2x + 1}$

Would you like help with evaluating, simplifying, or analyzing this function? Let me know if you'd like specific assistance on domain, range, or asymptotes, for example.

Here are five related questions for deeper understanding:

1. How do you find the domain of the function $f(x)$?
2. What are the vertical asymptotes of $f(x)$?
3. How can we find the horizontal asymptote of $f(x)$?
4. How do you calculate the x-intercept of this rational function?
5. How can we check for removable discontinuities in $f(x)$?

Tip: For rational functions, the denominator must not be zero to define the domain.
