If the number of subscriptions in thousands when the trend began was
, and
each year after that, the number has become
of what it was the year before, then

models the number of subscription in thousands where x represents the number of years since the trend has been observed.

If the function models the number of subscription in thousands where x represents the number of years since the trend has been observed, then
is
the number of subscriptions in thousands when the trend began.
That would be subscriptions when the trend began.
Also, means that every year the number of subscriptions gets multiplied by
,
and that means that the number of subscribers has
decreased by each year since the trend began.
