The function provided in the image is:

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

Let me know if you'd like me to solve or analyze this function further. For example, I can help with finding the domain, asymptotes, derivative, or other properties.

Here are a few questions related to this function:

1. What is the domain of $f(x)$?
2. How do you find the vertical asymptote of this function?
3. What is the first derivative of $f(x)$ and how can it be used to find critical points?
4. How can you find the horizontal asymptote of this rational function?
5. What are the intercepts of the function $f(x)$?

Tip: The domain of a rational function is all real numbers except where the denominator equals zero.
