Transcript text: Find the domain and range of the function graphed below.
Domain: $[-3,2)$
Range: $\square$
Solution
Solution Steps
Step 1: Find the Domain
The domain of a function is the set of all possible input values (x-values) for which the function is defined. In this graph, the x-values span from -3 to 2, inclusive of -3 but exclusive of 2 (indicated by the closed circle at -3 and the open circle at 2).
Step 2: Find the Range
The range of a function is the set of all possible output values (y-values) resulting from the input values in the domain. The lowest y-value on the graph is -4, and the highest y-value is 4. Both the highest and lowest points are included in the range because there are no open circles at those points.
