#### Slide 1 -Tekstslide

• 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 -Tekstslide

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

#### Slide 8 -Tekstslide

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.

#### Slide 15 -Tekstslide

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!

#### Slide 22 -Tekstslide

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

1, 2, 5 and 7
