Answer:
Number of turning points = 5.
Step-by-step explanation:
Turning points of a polynomial is the point where the graph of the polynomial changes its direction.
So, in order to find the number of turning points, we see at how many points the graph is changing its direction.
From the given graph, the graph changes its direction at 5 points. We can see it from the attached figure. Graph changes its direction at points A,B,C, D and E.
Therefore, number of turning points = 5.
