Example: If R is percent of maximum response and x is dose in mg, the dose- response curve for a drug is given by R = 100 1+100e-0.1x a) Graph this function. b) What dose corresponds to a response of 50% of the maximum? This is the inflection point, at which the response is increasing the fastest. c) For this drug, the minimum desired response is 20% and the maximum safe response is 70%. What range of doses is both safe and effective for this drug?
