Math Problem Statement

What could be the equation of the polynomial p based on the given graph?

Solution

The problem is asking to identify the equation of the polynomial p(x)p(x) based on its graph.

Steps to solve:

  1. Identify the Zeros (Roots): The graph crosses or touches the x-axis at specific points. These are the zeros of the polynomial. From the image:

    • Zeros are at x=3x = -3, x=1x = -1, and x=2x = 2.
  2. Determine the Multiplicity:

    • At x=3x = -3: The graph crosses the x-axis, so the zero has a multiplicity of 1.
    • At x=1x = -1: The graph bounces off the x-axis, indicating a multiplicity of 2.
    • At x=2x = 2: The graph crosses the x-axis, so the zero has a multiplicity of 1.
  3. Write the Polynomial: Using the zeros and their multiplicities, the polynomial can be written as: p(x)=a(x+3)(x+1)2(x2)p(x) = a(x + 3)(x + 1)^2(x - 2) where aa is a leading coefficient to be determined based on additional information (like the y-intercept or behavior as xx \to \infty).

  4. Check the End Behavior: Since the polynomial appears to rise to infinity as xx \to \infty, the leading coefficient a>0a > 0. Hence, aa is positive.

Final Equation:

The equation is likely: p(x)=a(x+3)(x+1)2(x2)p(x) = a(x + 3)(x + 1)^2(x - 2) where aa is a positive constant.
