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].
