6-64.

Dorinae is confused. She is making a $x → y$ table $y = | x + 1 |$. She is trying to find y when $x = –3$, but she is not sure if she should find the absolute value first, or if she should first add 1. Explain to Dorinae what she should do first. Justify your reasoning.

The absolute value symbol is a grouping symbol, like parentheses.
