[tex]\{ x|x \leq 1\}[/tex]
No... the domain is precisely those values of [itex]x[/itex] for which the function is defined. It isn't defined for [itex]x = -2 < 1[/itex], as you discovered a minute ago, so the domain can hardly be what you suggest here.

Your initial intuition, [itex]\{ x \ | \ |x| < 1 \}[/itex], was correct.
