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:

  1. Point C (2, 0):

    • This is a zero of the polynomial.
    • The graph crosses the x-axis at x=2x = 2.
    • Since it crosses the axis, the multiplicity of this zero is odd.
  2. Point D (-2, 0):

    • This is another zero of the polynomial.
    • The graph crosses the x-axis at x=2x = -2.
    • Since it crosses the axis, the multiplicity of this zero is odd.
  3. Point E (-1, 0):

    • This is another zero of the polynomial.
    • The graph touches the x-axis at x=1x = -1 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.

Tip: When analyzing the graph of a polynomial, always check how the graph interacts with the x-axis at each zero to determine the multiplicity.
