Question 1105073: As more and more people get their news online, the subscriptions to the Dorchester Daily has declined over the past years.
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.
What do the values in the function represent?

s(x)=0.9(.82)^x
s(x) is the number of subscriptions in 10,000s
0.9 represents 9000 subscriptions and was the initial value when x=0 years and 0.82^x=1
0.82^x represents an 18% annual decline where x=years.
