Summer 2021 Vista Virtual School Math 30-1 Assignment 3 7. Given the graph of the function f (x) = -- 3 +1 (x+ 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, after entering the body, a substance is eliminated at a rate that can be modelled by the function C(1) = , 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 ( ) = ( = )" 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 the original rate. The initial concentration of the substance is cut in half. 7
