What are the domain and range of this relation

Answer: Lower left corner (southwest corner)
Domain = {-2, 0, 1, 2, 5}
Range = {-5, -3, -1, 2, 3}
=============================================================
Explanation:
The domain is the set of allowed x value inputs. We simply list the x coordinates of each point shown on the graph. Those x coordinates are: -2, 0, 1, 2, 5. Use curly braces to indicate we're dealing with a set.
The range is the set of allowed output y values. We list the y coordinates this time and they are -5, -3, -1, 2, 3. These values are also surrounded by a pair of curly braces.
