1. **Problem:** Identify the vertical asymptote, horizontal asymptote, domain, and range of the function $$f(x) = -\frac{1}{x - 2} - 1$$ and sketch its graph.
2. **Vertical asymptote:** The vertical asymptote occurs where the denominator is zero, so solve $$x - 2 = 0$$ which gives $$x = 2$$.
3. **Horizontal asymptote:** For rational functions where the degree of numerator is less than denominator, the horizontal asymptote is $$y = $$ the constant outside the fraction, here $$y = -1$$.
4. **Domain:** All real numbers except where denominator is zero, so $$\{x \in \mathbb{R} : x \neq 2\}$$.
5. **Range:** The function approaches but never reaches the horizontal asymptote $$y = -1$$. Since the function is a transformed reciprocal function, the range is $$\{y \in \mathbb{R} : y \neq -1\}$$.
6. **Summary:**
- Vertical asymptote: $$x = 2$$
- Horizontal asymptote: $$y = -1$$
- Domain: $$(-\infty, 2) \cup (2, \infty)$$
- Range: $$(-\infty, -1) \cup (-1, \infty)$$
7. **Graph description:** The graph has two branches, one approaching the vertical asymptote at $$x=2$$ from left and right, and the horizontal asymptote at $$y=-1$$ from above and below.
