Using function concepts, it is found that the turning points of the graph are:

November 2000, when it goes from increasing to decreasing.

December 2000, when it goes from decreasing to increasing.
June 2001, when it goes from increasing to decreasing.

In a graph:

A function is increasing if it is pointing upwards.
If it is pointing downwards, it is decreasing.

A turning point is when the function changes from decreasing to increasing or vice-versa.

In this problem:

Initially, the function is increasing.
In month 3, that is, November 2000, it starts to decrease, thus, in November 2000, we have a turning point.
The next month, that is, December 2000, it starts to increase again, so it is another turning point.
It increases until month 9, which is June 2001, when it starts to decrease, being the final turning point.
