Question
### Calculus-Based Graphing of a Polynomial Function

To understand the behavior of the following polynomial function, you will sketch its graph using calculus principles. This exercise will help you answer the next four questions.

\[ y = \frac{x^3}{3} + \frac{x^2}{2} - 6x + 4 \]

#### Key Steps:

1. **Find the First Derivative (\( y' \))**
   - The first derivative provides information about the slope of the function, and it helps identify critical points (maximums, minimums, and points of inflection).

2. **Find the Second Derivative (\( y'' \))**
   - The second derivative gives information on the concavity of the function and helps determine the nature of critical points.

3. **Determine Critical Points**
   - Set the first derivative equal to zero to find critical points. These can indicate where the function has local maxima and minima.

4. **Analyze Concavity and Points of Inflection**
   - Use the second derivative to determine intervals where the function is concave up or down. Points where the concavity changes are called points of inflection.

5. **Sketch the Graph**
   - Use the critical points, points of inflection, and the behavior at infinity to sketch the graph accurately.

Use this sketch to answer subsequent questions about the function's behavior and properties.
