calculusfunctions · Answer

If $$\left| x \right|<a$$where a is a positive number, then$$-a <x <a$$
Start there.

anonymous · Answer

$$-1<\frac{x-1}{x+1}<1$$ I am stuck here. Next step is supposed to multiply -1 and 1 with the denominator but if $x+1<0$ the "<" sign would be ">" but how do I know whether $x+1<0$ or $x+1>0?$

well, u have two problems... 
first, -1 < (x-1)/(x+1) and 
(x-1)/(x+1) < 1 just to find solution of both!

anonymous · Answer

For first part: -x-1< x-1 2x>0 -> x>0 For second part x-1< x+1 0 < 2 -> useless. So x>0
