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.
