Math Problem Statement
Do you find any point or zero which has a multiplicity in the graph? If so, specify them with multiplicity and explain the reason.
Solution
The graph depicts a polynomial function with several points of interest. Let's analyze the points and zeros to determine if any have multiplicity.
Key Points on the Graph:
- A = (-1.569, -3.124)
- B = (0.319, 8.643)
- C = (2, 0) (Zero)
- D = (-2, 0) (Zero)
- E = (-1, 0) (Zero)
Determining Multiplicity:
-
Point C (2, 0):
- This is a zero of the polynomial.
- The graph crosses the x-axis at .
- Since it crosses the axis, the multiplicity of this zero is odd.
-
Point D (-2, 0):
- This is another zero of the polynomial.
- The graph crosses the x-axis at .
- Since it crosses the axis, the multiplicity of this zero is odd.
-
Point E (-1, 0):
- This is another zero of the polynomial.
- The graph touches the x-axis at and turns around.
- When the graph touches the axis and turns around, it indicates that the zero has an even multiplicity.
Conclusion:
- Point C (2, 0): Zero with odd multiplicity (likely 1, 3, 5, etc.)
- Point D (-2, 0): Zero with odd multiplicity (likely 1, 3, 5, etc.)
- Point E (-1, 0): Zero with even multiplicity (likely 2, 4, 6, etc.)
The key reason for determining multiplicity lies in how the graph interacts with the x-axis:
- If the graph crosses the x-axis at a zero, the multiplicity is odd.
- If the graph touches the x-axis and turns around at a zero, the multiplicity is even.
