because it has its highest concentration. Over time the concentration reduces and once it reaches a certain level, the medicine will no longer be effective. The concentration level of medicines can be most accurately modeled by rational functions. In this assignment, there are models for 5 different prescription medications. It is generally accepted that when a concentration of a medicine is below 0.15 mg/L. it is no longer effective. It is your job to determine how long each medicine is above the 0.15 mg/L level and rank them from longest relief to shortest relief.
