You can put this solution on YOUR website!
draw a graph with y=|x+21|, domain as a real numbers.
------------
You need to plot some points to obtain the graph.
Let x=-21, then y=|-21+21|=0; this gives you the point (-21,0)
Let x = -22, then y =|-22+21|=1 ; this gives you the point (-22,1)
Let x = -20, then y |-20+21}=1 ; this gives you the point (-20,1)
Keep this up to get as many points as you wnat.
------------
Plot your points on an xy-coordinate system and
draw a line thru those points; that is the graph you want.
