Which of the following is the parent function of all absolute value functions? f(x) = 3x
f(x) = |x|
f(x) = 2|x|
f(x)=x²

the 3rd on is correct

step-by-step explanation:

"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.
