Question 699296: It reads: A drug is injected into a patient and the concentration of the drug in the bloodstream, is monitored. The drug's concentration, Y, in milligrams per liter, after x hours is modeled by:
y=(5x)/(x^2+1)
Find the drugs concentration after 3 hours. I know the answer is 1.5 mg per liter, but I can't figure out how to write it out
