Pharmaceutical companies are interested in modelling the side-effect responses of medication. For example, the equation R(t) = 20t4 – 80t³ + 95t² – 30t can be used to model the side-effect response, where R(t) is the temperature in degrees Celsius above or below the normal body temperature (36.9°C) caused by an experimental drug t hours after it was administered. Due to the stress of temperature change on the body, a second drug is administered at the moment the patient's temperature starts to exceed 36.9°C. By applying the knowledge that you have learned about polynomials, algebraically, determine when the second drug will likely be administered. (4)
