At the start of soccer season, Tom weighed 160 pounds. He noticed that because of all the exercise he now gets, he is losing 2 pounds per week. Which of the following function rules represents this situation?

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
