Math Problem Statement
Solution
The problem is asking to identify the equation of the polynomial based on its graph.
Steps to solve:
-
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 , , and .
-
Determine the Multiplicity:
- At : The graph crosses the x-axis, so the zero has a multiplicity of 1.
- At : The graph bounces off the x-axis, indicating a multiplicity of 2.
- At : The graph crosses the x-axis, so the zero has a multiplicity of 1.
-
Write the Polynomial: Using the zeros and their multiplicities, the polynomial can be written as: where is a leading coefficient to be determined based on additional information (like the y-intercept or behavior as ).
-
Check the End Behavior: Since the polynomial appears to rise to infinity as , the leading coefficient . Hence, is positive.
Final Equation:
The equation is likely: where is a positive constant.
