Transcribed Image Text:### Graphs and Functions Matching Activity
**Instructions:**
Match the graphs with the functions from the Answer Bank below. Each graph represents exactly one function, and each function describes exactly one graph.
**Graphs:**
1. **Graph 1:**
- **Description:** This graph depicts a surface that slightly dips downwards in a symmetrical fashion from the center point.
2. **Graph 2:**
- **Description:** This graph shows a wavy surface with periodic rises and falls, forming a unidirectional wave pattern.
3. **Graph 3:**
- **Description:** This graph features a multi-peaked, wavelike surface.
4. **Graph 4:**
- **Description:** This graph displays a V-shaped surface with a sharp ridge running along the x-axis.
5. **Graph 5:**
- **Description:** This graph shows a flat plane surface that is slanted downward.
6. **Graph 6:**
- **Description:** This graph features a dome-like surface with a symmetrical rise from the center.
**Answer Bank:**
1. \( f(x, y) = \cos(y^2)e^{-0.1(x+y)} \)
2. \( f(x, y) = |x| + |y| \)
3. \( f(x, y) = \cos(x - y) \)
4. \( f(x, y) = \frac{1}{1+9x^2+9y^2} \)
5. \( f(x, y) = -\frac{1}{1+9x^2+y^2} \)
6. \( f(x, y) = \cos(x^2 + y^2)e^{-0.1(x+y)} \)
**Diagrams Explanation:**
- **Graph 1** pairs with the function:
- **Graph 2** pairs with the function:
- **Graph 3** pairs with the function:
- **Graph 4** pairs with the function:
- **Graph 5** pairs with the function:
- **Graph 6** pairs with the function:
Use the visual characteristics and the mathematical properties of the functions to find the appropriate matches.
