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(1) = te-k
where time i> 0 is measured in hours, and where k is some positive constant.
(a) Find all critical point(s) of the function A (where 1 > 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.
(b) Fill in the blanks in the following sentences. (Note: If you are not printing the exam, you can write out the
sentences and fill in the blanks.)
For larger values of k the t-value of the critical point would be (write "larger" or "smaller"), and for the
patient, this means that for larger values of k -
. (Write a sentence.)
Furthermore, for larger values of k the A-value of the critical point would be (write "larger" or "smaller"), and
for the patient, this means that for larger values of k,
- (Write a sentence.)
