Apatient 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
fx) = 50(0.60)*: 18 mg
fx) = 50(40)*; 80,000 mg
f(x) = 50(60)"; 180,000 mg
