g ( x) = absolute value of x /x and g (x) = x /x

i have to find the domain of each of the functions...what is the difference between them...

Be aware, however, that there is not a "second" and "third". The last two equations are for the

**same**function. And, in fact, $\displaystyle frac{x}{x}$ and $\displaystyle \frac{|x|}{x}$ have exactly the same domains- all x except 0.
