Answer 1

$\displaystyle\bf\\y=\left \{ {{2x-2 \ \ , \ \ x\geq 0 } \atop {\dfrac{1}{2} x-2 \ \ , \ \ x < 0} \right. \\\\\\x=-4 \ \ , \ \ -4 < 0 \ \ \Rightarrow \ \ y=\frac{1}{2} \cdot(-4)-2=-2-2=-4\\\\\boxed{y=-4}\\\\\\x=0 \ \ , \ \ x=0 \ \ \Rightarrow \ \ y=2\cdot 0-2=-2\\\\\boxed{y=-2}\\\\\\x=6 \ \ , \ \ 6\geq 0 \ \ \Rightarrow \ \ y=2\cdot 6-2=12-2=10\\\\\boxed{y=10}$
