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.
