After this lesson, you should be able to:

1. Calculate growth factors from a percentage increament/decreament
2. Distinguish between Lineair and Exponential growth, basis calculation
3. illustrate both exponential -  as well as lineair growth in a graph.

Featuring.......

• Two groups , identified by odd/even, selection by randomizer.
  
• Your explanation should not exceed the time of 9 minutes
  
• You should give the class a simple example

The answers: check your work.....

Any Questions about the former?

Any Questions about homework?

Did you perform well on this one?

😒🙁😐🙂😃

Lineair-and exponential growth and exponential decay; mark the axes !

Exponential v.s. Lineair growth/decay

Any questions?

To-do-list

• Next lesson: A32 and A34, O34
• To be completed for next lesson : T13, A16, A22, A27 (and O24, A26, but you did them as part of the lesson already..)

• Homework: watch https://www.youtube.com/watch?v=PsofqqQmaZo  , questionaire + make exc. O28, 33,O34

RECAP

Percentages and growth factors and tables and growth

Now  you are  able to:

1. Calculate growth factors from a percentage increament/decreament
2. Distinguish between Lineair and Exponential growth, basis calculation
3. illustrate both exponential -  as well as lineair growth in a graph.

Lineair growth: try this!
