Domain Rational Function
1. The problem asks us to find the domain of the rational function $$f(x) = \frac{5}{x - 6}$$ and understand its graph.
2. The domain of a rational function includes all real numbers except where the denominator equals zero because division by zero is undefined.
3. Set the denominator equal to zero to find excluded values:
$$x - 6 = 0$$
4. Solve for $$x$$:
$$x = 6$$
5. Therefore, the domain is all real numbers except $$x = 6$$. In interval notation, the domain is:
$$(-\infty, 6) \cup (6, +\infty)$$
6. The graph has a vertical asymptote at $$x = 6$$ where the function is undefined.
7. The graph approaches zero (the x-axis) horizontally as x approaches $$\pm \infty$$, so there is a horizontal asymptote at $$y = 0$$.
8. Summary:
- Domain: all real numbers except $$6$$.
- Vertical asymptote: $$x=6$$.
- Horizontal asymptote: $$y=0$$.
Final Answer: $$\text{Domain} = \{ x \in \mathbb{R} : x \neq 6 \}$$
