## Polynomial Function Analysis

### 2. Given the function \( f(x) = -x^2(x - 3)(x - 1) \)

a. **Find the x and y-intercepts:**

- **X-Intercepts:** Set \( f(x) = 0 \) and solve for \( x \).
- **Y-Intercept:** Evaluate \( f(0) \).

b. **Crosses or touches:**
- Analyze which roots the polynomial crosses the x-axis and which ones it just touches.

c. **End Behavior:**
- Determine what happens to \( f(x) \) as \( x \rightarrow \infty \) and \( x \rightarrow -\infty \).

d. **The Maximum Number of Turning Points:**
- The degree of the polynomial gives the maximum number of turning points.

e. **Intervals:**
- Identify the intervals where the function is increasing or decreasing.

f. **Graph:**

- The diagram represents the coordinate plane with labeled axes.
- **X-Axis:** Ranges from -4 to 4 with increments.
- **Y-Axis:** Ranges from -50 to 100 with increments.

Use this setup to sketch the graph of the polynomial function and analyze its behavior in detail.
