i understand the vertex is (-2, -3)

is there also a domain and range?

What an odd question. If it exists, there is a Domain and a range.

Domain - What can you put in? Start with All Real Numbers and rule things out. In this case, nothing is ruled out.

Range - What can you get out? Start with All Real Numbers and rule things out. In this case, that absolute value is NEVER negative. The very least you can get from that absolute value is zero (0). This makes the minimum value of the entire expression -3. We just ruled out everything less than -3.
