Question

Which scale factors produce a contraction under a dilation of the original image? Select each correct answer. ​−6​ ​−0.5​ 0.5 6

Answer 1

A contraction would make the image smaller.

A negative number reflects the image and changes the size based on the number.

To make an image smaller the factor needs to be less than 1

so -0.5 and 0.5 would make the image smaller since 0.5 is less than 1.

Answer 2

Hi There!

Question - Which scale factors produce a contraction under a dilation of the original image? Select each correct answer.

Answer: -0.5 and 0.5

Why - The reason I say this is because to make the image smaller the dilation has to be smaller than 1 and in this case -0.5 and 0.5 are smaller than 1.

Hope This Helps :)
