Math Problem Statement
Solution
The function provided is . Let's analyze its graph by examining the key properties:
-
Roots: The function has roots at , , and .
- At , the factor is linear (), so the graph will cross the x-axis at .
- At , the factor is cubic , so the graph will exhibit a "cubic" behavior, crossing the x-axis with a flattening near this point.
- At , the factor is squared , so the graph will touch the x-axis and bounce off (since it is an even power).
-
End Behavior: The highest degree term is (since expands to a degree 6 polynomial), which means:
- As , .
- As , as well (because the leading coefficient is positive and the degree is even).
-
General Shape:
- There is a bounce at ,
- A crossing at ,
- A cubic-type crossing at .
By comparing this behavior to the given graphs:
- Option A shows a bounce at , a crossing at , and another crossing at , matching the behavior of the function.
Thus, Option A is the correct answer.
