Question
The body absorbs and breaks down different drugs in different ways. Below is a table showing some
data for the amount (in mg, rounded to the nearest tenth) of three different drugs remaining in a
patient's body t hours after taking a 100 mg dose of each drug.

The description of three different drugs is provided below:
• The drug Linophine is broken down in such a way that the amount present in the bloodstream
can be modeled using a linearly decreasing function L(t).
• The drug Expinephrine is broken down in such a way that the amount present in the blood-
stream can be modeled using an exponentially decreasing function E(t).
• The drug Powerflo is broken down in such a way that the amount present in the bloodstream
can be modeled using a function of the form P(t) = a – 1.5tk which is decreasing and concave
down for t > 0.
(a) Use the provided information to match each of the drugs described above to one of the columns
of data in the table. Make sure you explain why the column of data fits the description of the
drug. (That is, the process of elimination is not sufficient reasoning.)
(b) Find formulas for L(t), E(t), and P(t).
