1. Problem Description
The problem asks us to find the domain and range of the given function represented graphically and express them using interval notation. The graph has a hole at and starts at .
2. Solution Steps
To determine the domain, we look at the -values for which the function is defined. From the graph, we observe that the function starts at and continues to , but there is an open circle at . The closed circle at indicates that is included. So the domain is .
To determine the range, we look at the -values covered by the function. From the graph, we can see that the minimum -value is 2 and the maximum is
9. Also the $y$-value corresponding to the open circle at $x = 4$ is $y = 3$. Since every $y$ value between 2 and 9 is included, the range is $[2, 9]$.
3. Final Answer
Domain: [-3, 4)
Range: [2, 9]
