Question 391706
<pre>
Here is the graph of y = |x|

{{{graph(400,400,-10,10,-10,10, abs(x))}}}

The difference between 

y = |x| 

and 

y = |x| - 3

is that 3 has been subtracted from the right side.  That
shifts the graph downward by 3 units.  Here is the graph of y = |x| - 3

{{{graph(400,400,-10,10,-10,10, abs(x)-3)}}}
