Answer:
The exponential decay function.
Step-by-step explanation:
The exponential decay function can be used to model the amount of medicine in a person's bloodstream after a certain amount of time. When a drug is administered to a persons bloodstream perhaps through intravenous injections, the exponential decay function measures the initial concentration of the drug and then after a time t, it notes the new concentration. To obtain the result, the equation below is used:
C(t)=C(0)e^(-kt)
where,
k= constant
C(0)= Initial concentration after the injection
C(t)= Concentration after time t
