Question

Which scale factors produce an expansion under a dilation of the original image?

Answer 1

2 and 7.5 Hope this helps :)

Answer 2

An expansion is the same as a dialation enlargement.

This occurs when the scale factor is greater than one. Therefore, 2 and 7.5 are the correct answer.

0.1 and 0.9 would cause a dialation reduction.
