Math Problem Statement
Solution
Based on the provided graph of a degree 5 polynomial, we need to determine the x-values of the roots and their multiplicities.
Analyzing the graph:
-
Root at x = -4:
- This root crosses the x-axis at and the behavior suggests it has multiplicity 1. This is because the graph crosses the x-axis sharply.
-
Root at x = 2:
- The graph touches the x-axis at without crossing it, indicating this is a root with multiplicity 2.
-
Other roots:
- The graph crosses the x-axis again near , which suggests a root at with multiplicity 1.
Updated table:
Root with x = | Multiplicity |
---|---|
-4 | 1 |
0 | 1 |
2 | 2 |

Here are 5 related questions:
- What is the general shape of a degree 5 polynomial based on its behavior at infinity?
- How does multiplicity affect the graph of a polynomial at its roots?
- What is the difference between even and odd multiplicity in terms of graph behavior?
- Can you identify other key features of polynomials based on their graphs?
- How do the number of roots and their multiplicities relate to the degree of the polynomial?
Tip: Always check how the graph behaves at the x-axis to determine the root's multiplicity—crossing means odd multiplicity, touching means even.
