A. -2
D. 2
"Expansion" means the magnitude of the scale factor is more than 1. Your choices for that are -2 and 2.
(0.75 and |-0.75| are less than 1.)
Answer: A. −2 and D. 2
Step-by-step explanation:
A scale factor (k) is number which is used to scale a figure.
It is basically used to either reduce or enlarge the size of the figure
A dilation is transformation which uses scale factor to produce the images of same shape as original but of different size.
From the given options , |-2|>1 and |2|>1 where as |-0.75|=0.75<1 and |0.75|<1
Therefore the scale factors produce a expansion under a dilation of the original image are : -2 and 2.
Hence, the correct options are A. −2 and D. 2 .
