For this problem, you do not need to find f'(x), because it consists of two straight lines that intersect. A single straight line is monotonic if it is not horizontal.

Treat f(x) as two separate parts:

f(x)=-(x+2) if x<-2, and

f(x)=x+2 if x≥-2.

So if the domain is given in [2,∞], it consists of a straight line and therefore has an inverse.

Follow the steps set out in your previous question to find the inverse, if necessary, or as practice.
