The answer is:
[tex]f(x)=\begin{cases}-x-2,if-6\le x\le-1 \\ -2,if-1Basically, we need to find the equation to three different lines.
The first one goes from x = -6 to x = -1
Then let's calculate the slope of the line. We can grab 2 points, (-6, 4) and (-5, 3). And we can use the formula for the slope of the line:
