**Title: Understanding Cubic Functions through Graph Interpretation**

---

**Objective:**

Write a cubic function based on the provided graph.

**Graph Description:**

- The graph depicts a cubic function with a blue curve.
- The x-axis ranges from -8 to 8, and the y-axis ranges from -9 to 4.
- Key points on the graph include:

  - (-6, 0): A point on the x-axis where the curve crosses.
  - (-3, 0): Another point on the x-axis where the curve crosses.
  - (0, -9): This point is the curve’s minimum or turning point.
  - (3, 0): A point on the x-axis, indicating another root.

**Function Representation:**

The task is to determine the cubic function \( f(x) \) that matches the graph based on these intercepts and turning points.

**Equation Template:**

\[ f(x) = \_\_ \]

Enter the cubic function that best represents the graph above, considering the roots and turning points.

**Analysis:**

The graph has three x-intercepts and one local minimum point. Use these characteristics to determine coefficients and compile the function formula. Consider the possibility of multiplicity in the roots and symmetry or transformations in determining the exact function.

---

**Interactive Component:**

Explore further how changes in coefficients affect the shape and position of the cubic function on the graph.

*Note: Please fill in the function based on your analysis of the graph provided.*
