N.R 1 and #3

Numerical Response The point (-1, 2) lies on the graph of y = f(x), which then undergoes a vertical and a 7. horizontal stretch. The corresponding point on the graph of the transformed function is (-4, 4). What is the vertical stretch factor? Hint: The y-coordinates are affected by a vertical stretch. . Which of the following sequences of transformations tell how the graph of y = 42x - 6 can be produced from the graph of y = v x? A. Vertical stretch by a factor of 2, horizontal stretch by a factor of , horizontal translation 6 units right. B. Vertical stretch by a factor of 4, horizontal stretch by a factor of 2, horizontal translation 3 units left. C. Vertical stretch by a factor of 4, horizontal stretch by a factor of - , horizontal translation 6 units left. D. Vertical stretch by a factor of 4, horizontal stretch by a factor of , horizontal translation 3 units right. Hint: Compare y = 4:2x - 6 to y = avb(x - h) + k. ixsay eni jueds beloslistat ro
