EXAMPLES OF DOMAINS AND RANGES FROM GRAPHS
Important notes about Domains and Ranges from Graphs: Remember that domain refers to the x-values that are represented in a problem and range refers to the y-values that are represented in a problem.Sometimes i
is continuous and made up of an infinite number of points, like a line, a ray, or even a segment.In a continuous graph, to determine the domain
, you should focus on looking left to right of the graph. In a continuous graph, to determine the range, you should focus on looking bottom to top of the graph. We use interval notation to help us describe the domain and range for graphs that represent continuous situations. Please review the following information to help you describe the domain and range for three different types of continuous graphs.Example 1: A continuous graph with two endpoints.
Domain: {-
Notice that this graph has two endpoints, so the graph starts and stops and the domain covers all x-values between the two endpoints which makes it a continuous graph. Since the left and right endpoints are at (-7, -3) and (5, 1), the graph covers all x-values between the x-values of -7 and -3. Notice that the first endpoint is a closed circle so it includes that point; but the second endpoint is an open circle, so it does not include that point. Therefore, the graph covers all x-values -7 AND all x- values < 5 we write that in interval notation as {-Range: {-y < 1}

Notice that the first endpoint is a closed circle so it includes that point; but the second endpoint is an open circle, so it does not include that point.
