Final answer:
The turning points of the function can be estimated by finding the x-values where the graph changes direction, which are x = -3, x = 0, and x = 4.
Step-by-step explanation:
The turning points of a function are the points where the graph changes from increasing to decreasing or from decreasing to increasing. We can estimate the turning points by looking for the x-values where the graph changes direction. From the given graph, we can see that there are three turning points:
- x = -3
- x = 0
- x = 4
