Respuesta :

Using it's concept, it is found that the average speed at which the plant's length increases between the 2nd and the 18th week is given by:

A. 2.2 centimeters per week.

What is the average rate of change of a function?

It is given by the change in the output divided by the change in the input.

In this problem, looking at the graph:

  • In the 2nd week, the height is of 7.5 cm.
  • In the 18th week, the height is of 42.5 cm.

Hence the rate is given by:

r = (42.5 - 7.5)/(18-2) = 2.2 cm/week.

Which means that option A is correct.
