9-112.

Kahlid is going to make a table to graph $y = \sqrt { x ^ { 2 } }$, but Aaron says that it would be a waste of time to make a table because the graph is the same as $y = x$.

1. Use Kahlid's equation to make the table and draw the graph.

2. As you can see, Aaron was wrong, but you did get a graph that you have seen before. What other equation has the same graph? Explain why this is reasonable.

$y = \left|x\right|$
