A drug response curve describes the level of medication in the bloodstream after a drug is administered. A surge function S ( t ) = At p e kt (where t > 0) is often used to model the response curve, reflecting an initial surge in the drug level and then a more gradual decline. If, for a particular drug, A =0.02, p =4, k =0.07, and t is measured in
