2 Given the graph of the function f (x) = - (x + 1) 2 a. Give a step-by-step explanation of how to graph f (x) using transformations of the graph of y = - 2 . (2 marks ) b. State the domain and range using set notation. (1 mark) 8. Suppose that after entering the body, a substance is eliminated at a rate that can be modelled by the function C (t) = () , where C is the concentration and t is time. Complete the following 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 Horizontal translation 5 units units of time. c (t ) = 2 right. Instead of reducing the concentration of the substance to zero, the body reduces the concentration of the substance toward 4 units. The substance is eliminated at a third of the original rate. The initial concentration of the substance is doubled
