Question

what is true about the dilation?
pre - image
image
it has a scale factor between zero and one and is a reduction.
it has a scale factor greater than one and is a reduction.
it has a scale factor between zero and one and is an enlargement.
it has a scale factor greater than one and is an enlargement.

Explanation:

Step1: Compare pre-image and image

The pre-image is larger than the image, so this is a reduction.

Step2: Relate to scale factor

For dilations, a reduction means the scale factor $k$ satisfies $0

Answer:

It has a scale factor between zero and one and is a reduction.
