Every minute 16% of the medicine is used up. This means that 84% of the medicine is left.
Amount of medicine left after 0 minutes have passed = 21 units
Amount of medicine left after 1 minute has passed = 21*0.84
Amount of medicine left after 2 minute have passed = 21*0.84*0.84 = 21*(0.84)2
Amount of medicine left after 3 minute have passed = 21*0.84*0.84*0.84 = 21*(0.84)3
Following this pattern,
Amount of medicine left after x minute have passed = 21*(0.84)x
f(x) = 21*(0.84)x
