Repeated scaling makes a curve - Paper 1

Read before answering

A continuous simulation uses Q=16 x (1/2)^t, with t in hours and Q in units, for 0<=t<=3. This is an invented model, not a measured scientific claim. On a SEPARATE squared-paper sheet label time horizontally from 0 to 3 and quantity vertically from 0 to 16. Calculate four whole-hour points, then sketch a smooth curve. For more accuracy, calculate extra points at tenths of an hour. Keep estimates distinct from exact values.
