Consider the concentration, C, (in mg/liter) of a drug in the blood as a function of the amount of drug given, x, and the time since injection, t. For 0 ≤ x ≤ 4 mg and t > 0 hours, we have C = f(x, t) = 28te¯(4-x)t ƒ(2,5) = Give a practical interpretation of your answer: ƒ(2,5) is A. the amount of a 2 mg dose in the blood 5 hours after injection. B. the change in concentration of a 5 mg dose in the blood 2 hours after injection. C. the concentration of a 2 mg dose in the blood 5 hours after injection. D. the change in concentration of a 2 mg dose in the blood 5 hours after injection. E. the concentration of a 5 mg dose in the blood 2 hours after injection. F. the amount of a 5 mg dose in the blood 2 hours after injection.
