Question:

After a medical drug is injected directly into the bloodstream, it is gradually eliminated from the body. Graph the following functions on the interval 30, 104. Use 30, 5004 for the range of A(t). Determine the function that best models the amount A(t) (in milligrams) of a drug remaining in the body after t hours if 350 mg were initially injected.

(a) A(t) = t2 - t + 350 

(b) A(t) = 350 log(t + 1)

(c) A(t) = 350(0.75)t 

(d) A(t) = 100(0.95)t
