What is turning point
In the context of a mathematical function or a graph, a turning point refers to a point where the direction of the curve changes from increasing to decreasing or vice versa.
At a turning point, the derivative of the function is either zero or undefined.
Investigating the given graph, it has 3 turning points. Theses points can be located on the following x-values
-1.5, 0, and 1.5
