Solve the problem. The first derivative of a person's body temperature, with respect to the dosage of x milligrams of a drug, is given by D'(x) =- 8 +7: One milligram raises the temperature 3.2 C. Find the function D(x) giving the total change in temperature as a function of x. A D(X) = In + 5.6 x + 2 B D(x) = 8 In |x + 2| + 3.2 C D(x) = In 8 - 3.2 x +2 D D(x) = 8 In x + 2| - 5.6
