Math Problem Statement
Number of turning points and roots?
Solution
To analyze the given polynomial graph , we need to identify the number of turning points and roots.
Turning Points
Turning points are points where the graph changes direction from increasing to decreasing or vice versa. These points are also where the first derivative of the polynomial is zero.
By observing the graph:
- The graph has a turning point between and (a local maximum).
- The graph has another turning point between and 0 (a local minimum).
- The graph has a turning point between 0 and 1 (a local maximum).
- The graph has a turning point between 1 and 2 (a local minimum).
Thus, there are 4 turning points.
Roots (Zeros)
Roots of the polynomial are the points where the graph intersects the x-axis.
By observing the graph:
- There is a root at .
- There is a root at .
- There is a root at .
Thus, there are 3 roots.
Summary
- Number of turning points: 4
- Number of roots: 3
