Sagot :

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.
