Graph $f ( x ) = | x - 6 | - 4$.

1. Explain how you can graph this without making an $x → y$ table, but using parent graphs.

   Hint (a):

   How is the graph transformed from $y = \left|x\right|$?

2. Graph $g ( x ) = \| x - 6 | - 4 |$. Explain how you can graph $g\left(x\right)$ without making an $x → y$ table by using your earlier graph.

   Hint (b):

   Think about what absolute value does to the graph of $y = x$.
