The function C(t) below describes the concentration of a drug in the bloodstream over time. In this case, the medication was taken orally. C is measured in micrograms per miller and t is
measured in minutes. The graph of C(t) is shown below.
Select all that apply. There are 3 comect answers

C(1)= 5t/0.01t^2+3.3

A. The concentration of the drug is decreasing on the interval (18, infinity) even though we know time doesn't go on forever.
B. There is no asymptotes for this graph because time can go on forever and time can be negative.
C. C(80)-6
D. After about 18 minutes, the drug concentration is about 13.8 micrograms per milliliter
The concentration of the drug is increasing on the interval
(-infinity, 18)
