Question

How many turning points are in the graph of the polynomial function? 4 turning points 5 turning points 6 turning points 7 turning points

Answer 1

5 turning points

Explanation:

It is 5 turning points because if you look at the graph you can see that there are 5 points at which the line turns a different direction.

Answer 2

Number of turning points = 5.

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.
