First we draw the graph of 



But there is a restriction of , therefore
we must chop it off except where it is directly above
or below the part where x is beteen -2 and 1, like this:



Next we notice that the restriction is ,
so we place open circles at the ends since the graph
has no point directly below the part of the x-axis where 
 is on the x-axis or directly above the x-axis
where  is on the x-axis.  The graph does not 
include the point (-2,-2) or the point (1,1). The open 
circles indicate that the graph does not include that point. 
 


Next we draw the graph of 



But there is a restriction of , therefore
we must chop it off except where it is directly above
the part of the x-axis where x is greater than 1, like this:



Next we notice that the restriction is ,
so we place a closed circle at the end since the graph
has a point directly above where  is on the
x-axis, since the graph includes point (1,2).



That's the graph of
