Math Problem Statement

Use the graph to identify zeros and multiplicity. Based on the graph, recall that zeros of a function are values of x at which y = 0. Considering each zero, what is the multiplicity of each zero?

Solution

The graph in the image represents a polynomial function, and you are asked to identify the zeros and their multiplicities.

Zeros of the Polynomial

  • Zero at x=4x = -4: The graph crosses the x-axis at x=4x = -4, and it appears to pass straight through without flattening out, which suggests this zero has multiplicity 1.
  • Zero at x=2x = 2: The graph touches the x-axis at x=2x = 2 and "bounces" off the axis rather than passing through it, indicating that this zero has multiplicity 2.

Common Errors

It seems like you input x=4x = -4 twice with the same multiplicity of 1, which led to a mistake in the second entry. You should only list x=4x = -4 once and indicate its correct multiplicity, which is 1.

Final Answer:

  • x=4x = -4 with multiplicity 1.
  • x=2x = 2 with multiplicity 2.

Would you like a further breakdown of how multiplicity affects the graph of a polynomial, or any other clarification?

Here are some related questions you might find useful:

  1. How can you determine if a zero has even or odd multiplicity based on the graph?
  2. What does a zero with multiplicity greater than 1 imply about the graph's behavior?
  3. How can you factor a polynomial using its zeros and their multiplicities?
  4. What is the general form of a polynomial given its zeros and multiplicities?
  5. How does the degree of a polynomial relate to the total number of zeros (counting multiplicity)?

Tip: A zero with odd multiplicity will cause the graph to cross the x-axis, while even multiplicity results in the graph bouncing off or just touching the axis without crossing it.
