Answer:
Domain: [-5, 4]
Range: [-3, 3]
Explanation:
Domain
The domain of a graph is the set of all possible input values (x-values).
A closed circle means the graph contains that point.
Therefore, the domain of the given graph is the x-values between (and including) the two endpoints of the curve.
A square bracket is used when the end value is included in the interval.
Therefore, the domain is [-5, 4].
Range
The range of a graph is the set of all possible output values (y-values).
From inspection of the given graph, the lowest y-value is -3 and the highest y-value is 3.
As these values are included in the interval, use square brackets.
Therefore, the range is [-3, 3].
