How do you find the domain and range of piecewise function y={sqrt(-x) for -4<=x<=0 and sqrtx for 0<=x<=4?

The domain is allready defined by the question
The range is what values the function can go to:
If
And for positive
Actually the description looks like an absolute function:
graph{sqrt(|x| [-5.546, 5.55, -2.773, 2.774]}
