the table of x and y values is shown in the attached pic(part of question)
we have to decide according that graph
given points are (0, 0) (–1, 0), (2, 0)
when we graph these points on graph they show an increasing line as shown in the attached pic
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.
