To turn the given graph into an equation, we'll analyze its key features, such as intercepts, turning points, and asymptotic behavior. 

**Steps to Determine the Polynomial Equation:**

1. **Identify Roots:**
   - The graph appears to have roots (where the graph crosses the x-axis) approximately at \(x = -3\), \(x = 0\), and \(x = 2\).

2. **Determine Turning Points:**
   - There are turning points at approximately \((x = -2, y = 6)\) and \((x = 1, y = 3)\).

3. **Estimate Polynomial Degree:**
   - The graph suggests a polynomial of degree 4 based on the number of turning points and roots.

Given this analysis, we propose the polynomial in the form \(y = a(x + 3)(x)(x - 2)^2\) because the root at \(x = 2\) appears to be of multiplicity 2 (the curve touches the axis at this point without crossing it).

4. **Solve for Coefficient \(a\):**
   - Using one of the turning points or another known point, we can solve for \(a\).

Let's use the turning point at \((1, 3)\) to solve for \(a\):

\[3 = a(1 + 3)(1)(1 - 2)^2\]
\[3 = a(4)(1)(1)\]
\[3 = 4a\]
\[a = \frac{3}{4}\]

Thus, the polynomial equation approximated from the graph is:
\[y = \frac{3}{4}(x + 3)(x)(x - 2)^2\]

This approximation assumes a reasonable fit given the observed features of the graph.
