**Task: Construct a polynomial function that has the following graph. Write the final answer as an expanded polynomial (not in factored form). Show your work.**

**Graph Description:**

The graph shows a polynomial function on a coordinate plane with the x-axis and y-axis marked. Key features of the graph include:

- The graph crosses the x-axis at \( x = -2 \), \( x = 0 \), and \( x = 3 \), implying these are roots of the polynomial.
- It appears to change direction at these points, indicating possible turning points or roots with multiplicity.
- The overall shape of the graph is typical of a cubic polynomial, showing one peak and one trough.

**Key Points and Behavior:**

1. **Intercepts:**
   - The graph intersects the x-axis at \( x = -2 \), \( x = 0 \), and \( x = 3 \).

2. **Shape:**
   - The graph starts from the negative side of the y-axis, rises to a local maximum, decreases to a local minimum, and rises again, typical of a cubic function.

Given these points, the polynomial could be represented by a function of the form \( f(x) = a(x + 2)(x)(x - 3) \).

To fully determine the function, the coefficient \( a \) would need to be found, often through additional points or specific conditions which are not provided in the question description.

In expanded form, with \( a = 1 \) (assuming leading coefficient adjustments aren't specified):

\[ f(x) = (x + 2)x(x - 3) \]
\[ = (x^2 + 2x)(x - 3) \]
\[ = x^3 - 3x^2 + 2x^2 - 6x \]
\[ = x^3 - x^2 - 6x \]

This polynomial should match the given graph's shape and intercepts when plotted.
