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

In the given graph, let's examine the zeros or x-intercepts to identify any multiplicity:

  1. Zero at D=(2,0)D = (-2, 0):

    • The graph touches the x-axis and then rebounds. This suggests a zero with even multiplicity. Given the behavior of the graph at this point (a turning point where the graph doesn't cross the x-axis), it is likely to be a zero of multiplicity 2.
  2. Zero at E=(1,0)E = (-1, 0):

    • The graph crosses the x-axis, indicating a zero with odd multiplicity. Since it appears to just cross the axis without any flattening or turning around, it likely has a multiplicity of 1.
  3. Zero at C=(2,0)C = (2, 0):

    • Similar to point EE, the graph crosses the x-axis, suggesting a zero with odd multiplicity. Again, it likely has a multiplicity of 1, as there is no indication of the graph flattening or turning around.

Summary of Multiplicities:

  • D=(2,0)D = (-2, 0) has a multiplicity of 2.
  • E=(1,0)E = (-1, 0) has a multiplicity of 1.
  • C=(2,0)C = (2, 0) has a multiplicity of 1.

Explanation:

  • A zero with even multiplicity (like D=(2,0)D = (-2, 0)) will touch the x-axis and bounce back without crossing it. This is characteristic of a zero where the graph changes direction at the x-axis.
  • A zero with odd multiplicity (like E=(1,0)E = (-1, 0) and C=(2,0)C = (2, 0)) will cross the x-axis. This means the function changes sign at this point.

Would you like any further details or explanations?

Here are 5 questions you can ask next:

  1. How does the multiplicity of a zero affect the shape of the graph at that point?
  2. What are the implications of having a zero with even multiplicity in a polynomial function?
  3. How can we determine the exact multiplicity of a zero algebraically?
  4. What is the significance of the leading coefficient in determining the end behavior of a polynomial function?
  5. How does the Fundamental Theorem of Algebra relate to the number of zeros of a polynomial function?

Tip: To confirm the multiplicity of a zero, look at the behavior of the graph near the zero and the corresponding factor in the polynomial equation.
