Domain: $\square$
Range: $\square$
Solution
Solution Steps
Step 1: Identify the Domain
The domain of a function is the set of all possible input values (x-values) for which the function is defined. From the graph, the function starts at x=−3 and ends at x=3. The point at x=−3 is included (solid dot), and the point at x=3 is not included (open dot).
Step 2: Identify the Range
The range of a function is the set of all possible output values (y-values) that the function can produce. From the graph, the function reaches a maximum y-value of 3 and a minimum y-value of -5. The point at y=3 is included (solid dot), and the point at y=−5 is not included (open dot).
