A patient is given a 50 mg dose of medicine. The medicine's effectiveness decreases every hour at a constant rate of
40%. What is the exponential decay function that models this scenario? How much medicine will be left in the
patient's system after 2 hours?
f(x) = 50(0.40): 8 mg
f(x) = 50(0.60)*; 18 mg
fx) = 50(40)*: 80,000 mg
f(x) = 50(60)*; 180,000 mg
