The vertices of a pre-image are located at points (12, 8), (6, -4), and (-2, 10). If the image has coordinates (6, 4), (3, -2), and (-1, 5), is this an expansion or a contraction?
Answered by MathMate
If you notice that all the coordinates of the image are half the corresponding values in the pre-image, this means that the transformation is a contraction about the origin, with a factor of 0.5.

Im sorry, I have no clue what you said. Could you break it down?

It gets smaller.
Answered by Yaz
so Its a contraction?
Answered by Yaz
okay, nvm i got it

ok, always sketch a graph
