At time t 2 0 (in hours since giving the drug) the concentration (in mg/L) is given by St t2+1' Graph the function c with a graphing device. (Round your answers to two decimal places.) A graphing calculator is recommended. C(t) = (a) What is the highest concentration of drug that is reached in the patient's bloodstream? c = mg/L (b) What happens to the drug concentration after a long period of time? 0 The concentration of the drug in the bloodstream goes to 0 mg/L. 0 Nothing. the concentration of the drug remains constant throughout its time in the bloodstream. O The concentration of the drug in the bloodstream is reduced by 50%. O The concentration of the drug in the bloodstream is naturally restored to its highest level.
