Exponential growth
Some things grow or decay in an exponential way. This means that for every time unit (e.g. a day) the metric changes with ± the same percentage.
If you can say "
it doubles every _ days
" => this means it has
exponential growth/increase
! If you can say "
it drops to half every _ days
", it has
logarithmic decay/decrease
