Solve the problem.A drug is injected into a patient and the concentration of the drug is monitored. The drug's concentration, C(t), in milligrams after t hours is modeled by C(t) = .What is the end behavior of this function? Describe what this means in practical terms.

A. as x ? ?, C(x) ? 1.67; After 1.67 hours, the concentration of the drug is at its greatest. B. as x ? ?, C(x) ? 0.83; After 0.83 hours, the concentration of the drug is at its greatest. C. as x ? ?, C(x) ? 1.67; 1.67 is the final amount, in milligrams, of the drug that will be left in the patient's bloodstream. D. as x ? ?, C(x) ? 0; 0 is the final amount, in milligrams, of the drug that will be left in the patient's bloodstream.
