Answer:
A. 3/2
Explanation:
What is dilation?
The original image is DEFG. It is called the pre-image
The dilated image is D'E'F'G' and is called image
A transformed image has the coordinates labeled with a '
In this case the transformed image is a dilation of the original pre-image. A dilated image is a cop.y of the pre-image but with either an expansion or a compression
If the image is larger than the pre-image it is an expansion, if smaller than the pre-image then it is a compression
With dilation, comes a scale factor which indicates how much a pre-image has been expanded or compressed
Solution
If you look at the two images, take any side in the pre-image and compare its length with the corresponding side you can find the scale factor
Here if you take a side, say DE = 4 and look at the corresponding side D'E' = 6you see that the DE side has been expanded with a scale factor of 6/4 = 3/2
This scale factor applies to all sides, so you need to take only one side to find the scale factor
Answer: Scale Factor of dilation = 3/2
This is option A
