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.

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 17 - Tekstslide

h = 256 \cdot 1, 25^{​ t ​ ​}

h = 300 \cdot 0, 2^{​ t ​ ​}

h = 64 \cdot 2^{​ t ​ ​}

h = 2 \cdot 3^{​ t ​ ​}

Slide 18 - Quizvraag

h = 256 \cdot 1, 25^{​ t ​ ​}

h = 300 \cdot 0, 2^{​ t ​ ​}

h = 64 \cdot 2^{​ t ​ ​}

h = 2 \cdot 3^{​ t ​ ​}

Slide 19 - Quizvraag

h = 256 \cdot 1, 25^{​ t ​ ​}

h = 300 \cdot 0, 2^{​ t ​ ​}

h = 64 \cdot 2^{​ t ​ ​}

h = 2 \cdot 3^{​ t ​ ​}

Slide 20 - Quizvraag

h = 256 \cdot 1, 25^{​ t ​ ​}

h = 300 \cdot 0, 2^{​ t ​ ​}

h = 64 \cdot 2^{​ t ​ ​}

h = 2 \cdot 3^{​ t ​ ​}

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
