Hi I need the answer to this Question Please

3. A drug is administered to a patient, and the concentration of the drug in the bloodstream is
monitored. At time t > 0 (in hours since giving the drug), the concentration (in mg/L) is given by
5t
c(t) =
t2 + 1
Graphing this may still help you here.
What is the highest concentration of drug that is reached in the patient's bloodstream?
When would this approximately happen?
b. How long does it take for the concentration to drop below 0.3 mg/L?
Give the domain and range of this function, in context, using interval notation.
d. Many rational functions have vertical asymptotes as a feature of their graphs. Why does c(t)
have no vertical asymptotes? What quick change could you make to this function to make it
now have at least one asymptote? Explain why it would now have an asymptote.
e. Find lim c(t). Explain your answer in the context of the problem.
а.
С.
