Slide 1 - Slide

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 - Slide

Factor not exactly the same

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

h = 256 \cdot 1, 25^{​ t ​ ​}

h = 300 \cdot 0, 2^{​ t ​ ​}

h = 64 \cdot 2^{​ t ​ ​}

h = 2 \cdot 3^{​ t ​ ​}

Slide 18 - Quiz

h = 256 \cdot 1, 25^{​ t ​ ​}

h = 300 \cdot 0, 2^{​ t ​ ​}

h = 64 \cdot 2^{​ t ​ ​}

h = 2 \cdot 3^{​ t ​ ​}

Slide 19 - Quiz

h = 256 \cdot 1, 25^{​ t ​ ​}

h = 300 \cdot 0, 2^{​ t ​ ​}

h = 64 \cdot 2^{​ t ​ ​}

h = 2 \cdot 3^{​ t ​ ​}

Slide 20 - Quiz

h = 256 \cdot 1, 25^{​ t ​ ​}

h = 300 \cdot 0, 2^{​ t ​ ​}

h = 64 \cdot 2^{​ t ​ ​}

h = 2 \cdot 3^{​ t ​ ​}
