### Tangent Line Problem

**Objective:**  
Find an equation of the tangent line to the graph of the function at the given point.

**Function and Point:**  
\[ y = \frac{1}{3}x^3 + 8x, \quad (2, 2) \]

**Equation of the Tangent Line:**  
\[ y = \text{\_\_\_\_\_} \]

**Instructions:**  
Use a graphing utility to graph the function and the tangent line in the same viewing window.

### Graphs Explanation

#### Graph 1:
In the first graph:
- **Axes:** The horizontal axis represents \(x\), and the vertical axis represents \(y\). Axis values range from -7 to 7.
- **Curves:**
  - The **blue curve** is the graph of the function \(y = \frac{1}{3}x^3 + 8x\).
  - The **red line** is the tangent line at the point (2, 2).
- **Behavior:**
  - The blue curve enters the window from the left going down, curves near the origin, passes through the point (2, 2), and continues upward.
  - The red line, representing the tangent, touches the curve at (2, 2) and extends with a slight upward slope.

#### Graph 2:
In the second graph:
- Similar axes and curve representations, but the graph is shifted showing more of the upper segment of the function and tangent, emphasizing their intersection point.

#### Graph 3:
In the third graph:
- The axes remain the same.
- **Additional Observations:**
  - The tangent line is seen more prominently, showing its linear trajectory through (2, 2) as it descends.

**Information Note:**
The small information icons on each graph probably provide further explanations or allow interactions to better understand the tangent line's behavior in relation to the curve.

### Conclusion

The visual representations clearly demonstrate the interaction between the function and its tangent line at the specified point. Adjust graph views as needed for better analysis when using graphing utilities.
