Work Step by Step

We are given the function: $g(x)=3|x+1|-3$ We start graphing with the basic function $a(x)=|x|$. We horizontally shift $a(x)$ by one unit to the left to get $b(x)=|x+1|$. Then we vertically stretch $b(x)$ by a factor of 3 to get $c(x)=3|x+1|$. Finally we vertically shift $c(x)$ 3 units downward to get $g(x)=3|x+1|-3$. We use 3 points: $(-2,0),(-1,-3),(0,0)$.
