Drugs that decay exponentially leave a residue in the body. By definition, the half- life of a drug is the time until half the initial dosage remains. Suppose a patient takes a tablet of the same drug every 2 half-lives forever. What is the upper limit to the amount of drug that can be in the body?

The graph shown is the graph of which function?
