Limits Horizontal Asymptote
1. **State the problem:** We are asked to find the limits of the function $g(x)$ as $x$ approaches positive and negative infinity, and to identify the horizontal asymptote(s) of $g(x)$ based on the graph description.
2. **Analyze the limit as $x \to \infty$:** The graph shows that as $x$ goes to positive infinity, $g(x)$ approaches $y=0$. This means:
$$\lim_{x \to \infty} g(x) = 0$$
3. **Analyze the limit as $x \to -\infty$:** The graph starts near negative infinity with a sharp increase, indicating that as $x$ goes to negative infinity, $g(x)$ tends to negative infinity:
$$\lim_{x \to -\infty} g(x) = -\infty$$
4. **Identify horizontal asymptote(s):** A horizontal asymptote is a horizontal line that the graph approaches as $x$ goes to $\pm \infty$. Since $g(x)$ approaches $y=0$ as $x \to \infty$, the horizontal asymptote is:
$$y = 0$$
5. **Summary:**
- $\lim_{x \to \infty} g(x) = 0$
- $\lim_{x \to -\infty} g(x) = -\infty$
- Horizontal asymptote: $y=0$
This matches the graph description where the curve approaches zero on the right and decreases without bound on the left.
