Suppose that 5 mg of a drug is injected into the bloodstream. Let f(t) be the amount present in the bloodstream after 1 hours. Interpret f(1)=4 and f(1) = -0.4. Estimate
1
the number of milligrams of the drug in the bloodstream after 1
hours.
What is the meaning of f(1) = 4?
OA. 1 hour after the drug was injected, the amount present in the bloodstream is rising at a rate of 4 mg per hour.
OB. 4 hours after the drug was injected, the amount present in the bloodstream is rising at a rate of 1 mg per hour.
OC. 4 hours after the drug was injected, the amount present in the bloodstream is 1 mg.
OD. 1 hour after the drug was injected, the amount present in the bloodstream is 4 mg.
What is the meaning of f'(1) = -0.4?
OA. 1 hour after the drug was injected, the amount present in the bloodstream is -0.4 mg.
OB. 1 hour after the drug was injected, the amount present in the bloodstream is falling at a rate of 0.4 mg per hour.
OC. 0.4 hour after the drug was injected, the amount present in the bloodstream is 1 mg
OD. 1 hour after the drug was injected, the amount present in the bloodstream is rising at a rate of 0.4 mg per hour.
