Work Step by Step
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: $[-2,+\infty)$
