Would you like a detailed explanation of how to analyze or work with this function? Let me know if you have any specific questions!

Here are five questions related to this function:

1. How do you find the domain of the function $f(x) = \frac{2x - 1}{x + 4}$?
2. What is the vertical asymptote of this function?
3. How do you determine the horizontal asymptote of $f(x)$?
4. How would you find the intercepts (x-intercept and y-intercept) of the function?
5. How can you sketch the graph of $f(x) = \frac{2x - 1}{x + 4}$?

Tip: When working with rational functions, always start by analyzing the domain to identify any restrictions caused by the denominator.
