3. Suppose that when a patient takes a blood thinner drug, the amount of drug (in mg) in the patient's blood can be modelled by: A(t) = te -kt where time t > 0 is measured in hours, and where k is some positive constant. (a) Find all critical point(s) of the function A (where t > 0) and determine if they are local maximum(s) or minimum(s). Remember to find both t- and A-values (i.e. both coordinates of the point). You should answer with exact values, and your answers might depend on k.

Suppose that when a patient takes a blood thinner drug, the amount of drug (in mg) in the patient's
blood can be modelled by:
A(t) = te
where time t > 0 is measured in hours, and where k is some positive constant.
(a) Find all critical point(s) of the function A (where t > 0) and determine if they are local maximum(s) or
minimum(s). Remember to find both t- and A-values (i.e. both coordinates of the point).
You should answer with exact values, and your answers might depend on k.
