There are two horizontal asymptotes in the graph of a signum function. So, there should practically be 2 values of 'y' for x=infinity. Please explain this.

If -5/6 does not come under domain of f(x), then we should not get value of f(-5/6) but we are getting the value of f(-5/6)= -6/11 as f(-5/6) = 2/(|3-|(-5/6)-1|-5(-5/6)|-9) by putting x=(-5/6) =2/(|3-|(-11/6)|+(25/6)|-9) =2/(|3-(11/6)+(25/6)|-9) [ since |-11/6|=11/6 ] =2/{|(18-11+25)/6|-9} =2/{|32/6|-9} =2/{(32-54)/6} =2/(-22/6) =(-6/11) similarly f(11/4) = 4/7 And if (-5/6) and (11/4) are not the domain of f(x). How can i get any value at that point. Please clear my doubt

In First Case , we have x-1>=0, this means that we have to consider all the values greater than equal to 1, and therefore should we remove the value (-5/6) from the domain ? Similar is the case with the value (11/4) in the second case which is greater than 1. According to me the domain should be R-{-7/4,13/6}. Am a right here? Please explain
