Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.
Please see the attached image below, to find more information about the graph
The equation is:
f(x) = 2x+2 , x < -3
f(x) = x, x = -3
f(x) = - x -2 , x > -3
From the graph, we can see that the values are
y = -6; -3; 0
