[15 points) A model for the concentration ofa drug in the bloodstream 1 hours after the administration of the drug is C(t) : (LL-3:294"t where t is measured in #g/mL. [a] Find the vertical and horizontal asymptotes of C(t]. [b] Find the local extrema {maxima and minimal and the intervals of increase and decrease of C(t). [cl Find the inection points and intervals of concavity of C(t). (d) Sketch the graph of C(t). [el Explain the shape of the graph of C(t) in biological terms. Specifically. what do the local extrema. the inflection points, and any asymptotes represent
