The activity of a radioactive isotope is measured as 800 Bq800\text{ Bq}800 Bq.

This initial measurement is plotted as a point at (0,800)(0, 800)(0,800) on the graph grid in Figure 1.

The half-life of this radioactive isotope is 12 hours.

Use this information to plot three more points on the grid in Figure 1 to show how the activity of the isotope changes over a period of 36 hours. Figure 1: Graph of Activity against Time
