State the domain and range using set notation. (1 mark) 8. Suppose, after entering the body, a substance is eliminated at a rate that can be modelled by 1 r the function C (t) = [) , where C is the concentration and t is time. Complete the following 2 chart to match the scenarios as shown. (3 marks) Scenario Transformed Description of Transformation Equation A second substance delays the elimination of the first substance for 5 1 3'5 Horizontal translation 5 units units of time. C0) = [a] right. Instead of reducing the concentration of the substance to zero, the body reduces the concentration of the substance toward 10 units. The substance is eliminated at triple
