Question
find the vertical asymptote

Transcribed Image Text:This graph illustrates a rational function with an asymptote and a highlighted point. Here's a detailed description to help understand the graph better:
### Graph Description:
1. **Axes and Grid**:
- The graph is plotted on a Cartesian coordinate system with a grid.
- The x-axis and y-axis are labeled from -8 to 8.
- The x-axis extends horizontally, and the y-axis extends vertically.
2. **Asymptote**:
- A dashed vertical red line at \( x = -2 \) indicates the presence of a vertical asymptote.
- This suggests that the function approaches infinity as \( x \) approaches -2 from the left and negative infinity as \( x \) approaches -2 from the right.
3. **Function Behavior**:
- The graph of the function is drawn in red.
- For \( x \) less than -2, the function decreases rapidly as it approaches the vertical asymptote from the left. As x approaches \( -2 \) from the left, the y-value approaches positive infinity.
- For \( x \) between -2 and positive infinity, the graph increases from negative infinity at \( x = -2 \), crosses the y-axis, passes through an indicated point on the graph, and extends towards positive infinity as \( x \) grows larger.
4. **Highlighted Point**:
- A red dot is placed on the graph at the coordinates \( (2, 1) \).
### Key Notes:
- Understanding the behavior of the function near the asymptote is crucial. It affects the domain of the function, excluding x = -2 because the function tends to infinity or negative infinity at this point.
- The horizontal extension of the graph on both sides shows the end behavior, indicating how the function behaves as \( x \) approaches positive and negative infinity.
- The red dot indicates a specific value of the function at \( x = 2 \), which is \( y = 1 \).
This graph helps visualize the relationship between \( x \) and \( y \) for a given rational function, illustrating how it behaves near critical points and far from the origin.
