## Description of the Graph Transformation

The task is to describe how the graph of the given function can be obtained from one of the basic graphs.

### Function:
\[ 
g(x) = -\frac{1}{3}(x+2)^2 
\]

### Steps to Graph the Function:

1. **Start with the graph of:** (Select the appropriate basic function from options, such as \( y = x^2 \)).
2. **Shift it:** (Choose between left or right and specify the number of units).
3. **Units:** (Specify the number of units the graph is shifted).
4. **By multiplying each by:** (Specify the factor to multiply; in this case, by -1/3).
5. **Reflect it across the:** (Select the axis of reflection, such as x-axis or y-axis).

### Graphical Explanation:

- **Basic Graph:** Begin with the graph of a basic quadratic function, typically \( y = x^2 \).
- **Horizontal Shift:** Adjust the graph horizontally according to \( (x+2)^2 \), indicating a shift 2 units to the left.
- **Vertical Stretch/Compression and Reflection:** Multiply by \(-\frac{1}{3}\) to compress vertically and reflect it across the x-axis, indicating a downward opening.

This step-by-step process helps in visualizing how transformations affect the graph of the quadratic function.
