Math Problem Statement
Solution
Let's analyze the graph and the problem.
The graph of has the following characteristics:
- Roots: The graph crosses the x-axis at and . This means these values are roots of the polynomial .
- Behavior near the roots:
- At , the graph touches the x-axis and bounces off. This indicates that is a root with even multiplicity (likely a square, ).
- At , the graph also touches the x-axis and bounces off. This indicates that is a root with even multiplicity (likely ).
Now, let’s analyze the options:
- A. : The roots would be and , which do not match the graph.
- B. : The roots would be and , but the graph shows even multiplicities for these roots, and this option only provides multiplicity 1.
- C. : The roots are and , both with even multiplicities. This matches the behavior of the graph.
- D. : The roots are and , both with even multiplicities. However, the factors here are reversed from what is needed to match the graph.
Thus, the correct answer is C. .
