The graph provided shows a degree 4 polynomial \( f(x) \), and we are tasked with finding the factored form of the polynomial. Here's how we can proceed based on the visual information:

### 1. **Roots**:
We can identify the roots (x-intercepts) from the graph, which are the points where the polynomial crosses the x-axis:
- \( x = -4 \)
- \( x = 0 \)
- \( x = 1 \)

### 2. **Multiplicity**:
We can observe the behavior of the graph at these roots to infer the multiplicities:
- At \( x = -4 \), the graph touches the x-axis but doesn't cross it, indicating a root with even multiplicity. Since the degree of the polynomial is 4, this root likely has multiplicity 2.
- At \( x = 0 \), the graph crosses the x-axis, indicating a root with odd multiplicity. This root likely has multiplicity 1.
- At \( x = 1 \), the graph again crosses the x-axis, suggesting another root with multiplicity 1.

### 3. **Factored Form**:
Given this information, the factored form of \( f(x) \) can be written as:
\[
f(x) = a(x + 4)^2 x (x - 1)
\]
where \( a \) is a constant coefficient that can be determined by looking at other points on the graph, such as the y-intercept or a maximum/minimum point. From the graph, we can see that the polynomial has a local minimum around \( y = -5 \), which might help determine \( a \). 

Since no specific y-values are given beyond the intercepts, we leave \( a \) as an arbitrary constant for now.

### Summary:
The factored form is:
\[
f(x) = a(x + 4)^2 x (x - 1)
\]
Would you like to explore how to determine the value of \( a \), or any other details?

Here are 5 related questions:
1. How do we determine the constant \( a \) from the graph?
2. What happens if a polynomial root has higher multiplicity?
3. How can we use the degree of a polynomial to predict the shape of its graph?
4. What is the significance of a root where the graph touches but does not cross the x-axis?
5. Can we use calculus (like the derivative) to verify the behavior of the graph at specific points?

**Tip**: Always check the multiplicities of roots by observing whether the graph crosses the x-axis (odd multiplicity) or just touches it (even multiplicity).

The graph of the polynomial f(x) is given below. If f(x) has degree 4, find the factored equation for f(x).
