# Need to find an image.

Demonoid
I've given a function where f: R->R, and need to determine an image(or range):

f(x) = x/(1+|x|)

I've pretty sure the image is R, but I'm not positive:

Heres my attempt:

y/1 = x/(1+|x|)
y(1+|x|) = x
y+ y|x| = x
y|x| = x - y... I'm kinda stuck here, since I can't determine an image from this ???

any help is welcome !
