Answer:
Domain: (-2 , 3]
Range: [-3, 2)
Step-by-step explanation:
Domain is all the x's on the graph. (If you have an equation, then it's all the numbers that are allowed to be x)
Range is all the y's on the graph (or if you have an equation, all the possible y outcomes)
Open dot endpoint means that point is not included in the set (domain and range are sets of numbers) Closed dot means the point is included.
You didn't get this math question right. But look for all the x's for the domain, and all the y's for the range.
