Slide 1 - Diapositive

  • Determine the factor when there is exponential growth.
  • Determine the formula if you have the table for exponential growth between two variables.
  • Determine if a table describes exponential growth.
  • Calculate missing numbers in an exponential growth table.

Slide 2 - Diapositive

Factor not exactly the same
In some exponential growth processes the factor is not exactly the same. This can be caused bij rounding results.

Check for exponential growth
  1. Calculate the factor for each 
        pair of consecutive units of 
        time.
   2. Check whether the factor is 
        aproximatly the same for the 
        entire table.

Calculate missing numbers
- To calculate the next 
   number in a table, 
   multiply by the factor
- To calculate the previous 
   number in a table, devide 
   by the factor
             Actualy working with the formula is easier!

Conclusion:
  • Growth factors may differ slightly due to rounding off
  • Check if a table shows an exponential growth by calculating the growth factor of each consecutave interval
  • Determine unknown values in table by 
      using the formula
