The graph you've provided represents the function \( g(x) \), which appears to be a polynomial function based on its curvature and behavior. Let's break down the key features of this graph:

### Observations:
1. **Roots (x-intercepts)**: The graph crosses the x-axis at approximately \( x = -2 \), \( x = 3 \), and \( x = 5 \).
2. **Turning points**: 
   - The function reaches a maximum point near \( x = 0 \) with a value slightly above \( y = 1 \).
   - There is a local minimum near \( x = 4 \), where \( y \) is close to \( -2 \).
3. **End behavior**:
   - As \( x \to -\infty \), \( g(x) \to -\infty \) (as seen from the arrow on the left).
   - As \( x \to +\infty \), \( g(x) \to +\infty \) (as seen from the rising part of the curve on the right).

Based on this information, the general shape suggests that \( g(x) \) is likely a **cubic polynomial**. The roots suggest that the function could be factored as:

\[
g(x) = a(x + 2)(x - 3)(x - 5)
\]

Where \( a \) is a constant that controls the stretch and direction of the graph. 

### Next Step: Find \( a \)
To find \( a \), we can use the information from one of the turning points or y-intercepts. For example, the graph shows that \( g(x) \) has a y-intercept around \( (0, 1) \).

Substitute \( x = 0 \) and \( g(0) = 1 \) into the equation to find \( a \):

\[
g(0) = a(0 + 2)(0 - 3)(0 - 5) = 1
\]
\[
a(2)(-3)(-5) = 1
\]
\[
a(30) = 1
\]
\[
a = \frac{1}{30}
\]

### Final Equation:
Thus, the equation for \( g(x) \) is approximately:

\[
g(x) = \frac{1}{30}(x + 2)(x - 3)(x - 5)
\]
