A graphing calculator is recommended. A dmg ls administered to a patient, and the oonoentnatlon of the drug in the bloodstream is monitored. At time t 2 0 {In hours since giving the drug) the conoentration (in mgfL) is given by 7: 8+4" Graph the function 1: with a graphing device. (Round your answers to two decimal places.) C(t) = (a) What is the highest ooncentration ofdrug that is reached In the patient's bloodstream? c = mglL (b) What happens to the drug concentration after a long period of time? Q The concentnatlon of the drug in the bloodstream is natunally restored to Its highest level. 0 The concentnation of the drug in the bloodstream goes to D mgfL. 0 Nothing. the conoentration of the drug remains constant throughout its time in the bloodstream. O The oonoentnation of the drug in the bloodstream is reduoed by 50%. (c) HowI long does ittake for the conoentration to drop below 0.3 mg/L? 1' = hr Need Help?
