10 How is the graph of -1 = x' related to the graph of y = x' a. y = x has been stretched horizontally c. y = x has been stretched vertically about the y-axis by a factor of 3 about the x-axis by a factor of 3 b. y = x has been stretched horizontally d. y= x has been stretched vertically about the y-axis by a factor of - about the x-axis by a factor of - 11 The function f(x) = Vx +5 is transformed by a translation of 2 units down and 4 units to the left. The transformed function passes through the point (18,y). To the nearest hundredth, the value of y is 12 The graph of y = -is transformed to the graph of y = 5(x-2) +4 by a series of transformations. One of these transformations is a vertical stetch about the x-axis. The scale factor of the vertical stretch. to the nearest tenth, is 13 The domain and the range of the funtion y = - V-x+ 1 are respectively, all real numbers such that a. x21,y20 . x5-1,y20 b. x2-1,ySO d. xSlyso Use the following information to answer the next two questions. y =f(x) is a continuous function with domain x -4 S x $ 16,x e R. and range 14 SYS16, VER 14 The domain of the function y = V/(x ) is X/ 4 Sx 5 16.
