Step-by-step explanation:

The function s (x) = 0.9 (.82) ^x models the number of subscription in tens of thousands where x represents the number of years since the trend has been observed.

s (x) represents the number of subscriptions to the Dorchester Daily in a given year.

0.9 in ten thousands represents the initial number of subscriptions to the Dorchester Daily in a given year.

0.82 represents the rate at which the number of number of subscriptions to the Dorchester Daily is declining. The rate in percentage is 100 - 82 = 12% each year.

x represents the number of years since the trend has been observed.
