Identify the transformations of the graph of ƒ (x) = x 3
that produce the
graph of the given function g (x). Then graph g (x) on the same coordinate
plane as the graph of ƒ (x) by applying the transformations to the
reference points (-1, -1), (0, 0) , and (1, 1).

g (x) = 2 (x - 1)^3-1

why is the answer: ( I don't get the vertical stretch part)

The transformations of the graph of ƒ (x) that produce the graph of
g (x) are:
• a vertical stretch by a factor of 2
• a translation of 1 unit to the right and 1 unit down
thank you sooooo much

if you can explain the vertical stretch versus horizontal stretch versus compression

  1. Think about the axis (horizontal x, versus vertical y) and then think about compression (getting fatter) and stretch (getting skinnier). You might want to graph a few to see if you can see the results. You might want to also go over the notes your teacher gave you : )
