Write domain and range of graph.

A. Domain: (-3, 3] and Range: [-3, 6]

Step-by-step explanation:

The domain is all of the shown values on the x-axis for a graphed line, the range is all of the shown values on the y-axis for a graphed line. Let's start with the domain. On the very left, we can see an open circle at the point (-3, -3). An open circle means that the point doesn't include the value that it is on, so the line actually starts at 3.0001 (an infinite amount of zeroes after the decimal point). When there is an open point, we use parenthesis in interval notation, so we can eliminate B. On the very right, there is a line at (3, -3) that has a closed dot, which means it includes 3, so the domain is (-3, 3). Now for the range. The lowest point on the y-axis is -3, and it has a closed point, so we will use a square bracket ([), the highest point is 6 (no closed point, just a line, so square bracket still), so our range is [-3, 6].
