The graph shows the data points in the table and the exponential regression model associated with the data.

A 2-column table with 5 rows. The first column is labeled days after treatment with entries 2, 4, 6, 8, 10. The second column is labeled number of weeds with entries 100, 26, 6, 2, 1. A graph shows days after treatment labeled 1 to 11 on the horizontal axis and number of weeds on the vertical axis. A line shows a downward trend.
Based on the graph of the regression model, which is true?

The number of weeds is decreasing by a multiplicative rate.
The number of weeds is increasing by a multiplicative rate.
The number of weeds is decreasing by an additive rate.
The number of weeds is increasing by an additive rate.

The number of weeds is decreasing by a multiplicative rate.

Explanation: an exponential (regression) model implies multiplicative (percent) change over time, and the data show a rapid decrease (exponential decay).
