Answer:
the scale factor k is between 0 and 1
Step-by-step explanation:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
A dilation with the larger image than initial figure is called an enlargement.
A dilation that the smaller image than initial figure is called a reduction.
Thus, if the image is smaller than the original figure, then the scale factor k is between 0 and 1.
