The function is:

This is an exponential decay function because the base is between 0 and 1:

So the number of registered voters is decreasing over time.

Since represents the number of years since 2001:

To determine the fastest average decrease, compare the average rates of change. A faster decrease means the average rate of change is more negative.

For 2001 to 2007:

So from 2001 to 2007, the number of registered voters decreased by about:

For 2007 to 2008:

For 2008 to 2021:

For 2009 to 2012:

Now compare the decreases:

The most negative rate is:

That means the fastest average decrease happened from:

The graph is a logistic growth function.

A logistic function often has an S-shape. It begins by increasing slowly, then increases faster and faster, and later levels off as it approaches a maximum carrying capacity.

From year 1 to year 9, the graph is rising and becoming steeper.

That means:

and the slope is getting larger, so:

Therefore, the correct answer is:

From to about , the graph is decreasing, but it is flattening as it approaches a minimum. This means the number of raffle tickets sold is decreasing at a slower rate:

After the minimum, from about to , the graph increases and becomes steeper. This means the number of raffle tickets sold is increasing at a faster rate:

So the correct description is:
