Transcribed Image Text:### Understanding Horizontal Asymptotes
**Question:**
What is the equation for the horizontal asymptote of the graph of the function shown?
**Graph Illustration:**
The provided graph displays a function along with its asymptotes on the Cartesian plane.
- **X-Axis Range:** -8 to 8
- **Y-Axis Range:** -8 to 8
The graph depicts two asymptotes:
1. **Vertical Asymptote at \( x = 0 \)** (dashed vertical line).
2. **Horizontal Asymptote at \( y = 4 \)** (dashed horizontal line).
The curve approaches these asymptotes but never intersects them.
**Multiple Choice Options:**
- \( \circ \) \( y = 4 \)
- \( \circ \) \( y = 2 \)
- \( \circ \) \( x = 2 \)
- \( \circ \) \( x = 4 \)
**Answer Explanation:**
To determine the horizontal asymptote, observe the behavior of the function as \( x \) approaches positive or negative infinity. The graph clearly shows that the function approaches the line \( y = 4 \).
**Correct Answer:**
\( \bullet \) \( y = 4 \)
This indicates that as \( x \) moves towards positive or negative infinity, the value of \( y \) gets closer and closer to 4, making \( y = 4 \) the horizontal asymptote of the function.
