5. Suppose, after entering the body, a substance is eliminated at a rate that can be modelled by the function C : (%)f, where C is the concentration and t is time. Transform this function to match each of the following scenarios. [Hint: Only one transformation is required in each case.] Description Transformed Description of Transformation Equation The initial concentration of the substance is tripled. The substance is eliminated at one quarter of the original rate. A second substance delays all elimination of the first substance for 4 units of time. Instead of reducing the concentration of the substance toward 0, the body reduces the concentration of the substance toward 20 units
