## Algebra 1: Common Core (15th Edition)

a) The graphs have the same shape. Notice each point on the right graph is 4 units higher than the corresponding point on $y = |x|$. The graph is $y=|x| + 4$ b) $y=|x|$ The domain of the expression is all real numbers: $(-\infty, \infty)$. Range: $[0,+\infty)$ $y=|x|-2$ The domain of the expression is all real numbers: $(-\infty, \infty)$. Range: $[-2,+\infty)$
