Tutorial Exercise The reaction R to an injection of a drug is related to the dosage x (in milligrams) according to R(x) = x2(710 - -) where 1420 mg is the maximum dosage. If the rate of reaction with respect to the dosage defines the sensitivity to the drug, find the sensitivity. Step 1 We are given that the reaction R to an injection of a drug is related to the dosage x (in milligrams) according to R(x) = x2 (710 - 2 ) where 1420 mg is the maximum dosage. We want to find the sensitivity to the drug, which is defined as the rate of change of reaction with respect to the dosage. Thus, we want to find R'(x). Since R(x) is a product of two functions, we can find the derivative by using the ---Select--- V Rule. R'(x ) = *2( - ) + (710 - -) (
