Sometimes
we have equations where the right side



is inside
absolute value lines. 


Like: 


Y
= X^{2}  4






So what
happens then? 





What we
do is ... 





Step
1) 


Graph the equation without the absolute value lines. 











Step
2) 


Pretend the X axis is a mirror. 


Everything
that is below it gets reflected back the same distance above it. 








That's
it! 


If the
equation without the absolute value lines included the point (1,3), 


the
equation with the absolute value lines includes the point (1,3). 








Ya know,
this reflection stuff will work with ANY equation like this ...
