Without the image, I can't determine if the graph is a function or provide the specific domain and range. However, I can provide you with the criteria for identifying whether a graph represents a function.
To determine if a graph represents a function, you can use the vertical line test: If any vertical line intersects the graph at more than one point, then the graph does not represent a function.
If the line passes through multiple points (for example, if it has the same x-value for different y-values), then it is not a function. If each x-value has exactly one corresponding y-value, then it is a function.
If you can describe the placement of the points in relation to the line or provide coordinates, I'd be happy to help you analyze it further!
