The given function $f(x)$ from the image is:

$f(x) = \frac{4 - 3x - x^2}{x^2 - 1}$

Would you like to solve this equation, analyze its properties (like asymptotes or domain), or find something specific, such as the derivative or integral?

Here are a few possible next steps:

1. Simplify the function and identify any factorization.
2. Find the domain of $f(x)$.
3. Identify any vertical or horizontal asymptotes.
4. Take the derivative to analyze the function’s behavior.
5. Find the critical points and analyze them for extrema.

Tip: If the denominator equals zero, the function is undefined at those points, which could help you find vertical asymptotes or restrictions in the domain.
