1. Only a vertical translation is applied to the graph of y = x -6), so that after the translation the image graph passes through the point (4, 7). A function that describes the graph of the translated image is Dy =x -6 +9 Dy =x -6 +3 Oy =x -6 +5 Dy =x -6 -52. The graph of f (x) = 2 is transformed to produce the graph of g (x) = 8(2x)2. When described as a single transformation, the graph of g (x) =8(2x) may be obtained from the graph of f (x) = x2 by stretching vertically by a factor of 2 about the x-axis stretching vertically by a factor of 32 about the x-axis stretching vertically by a factor of 16 about the x-axis stretching vertically by a factor of 4 about the x-axis
