To determine the domain of a function from its graph, examine the horizontal extent of the graph. Identify all the x-values for which there are corresponding y-values. If there are any breaks, holes, or vertical asymptotes in the graph, those x-values are excluded from the domain. The domain can then be expressed in interval notation, indicating any restrictions found.
If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
I cannot see the graph you are referring to. However, to determine the domain of a function, you need to identify all possible input values (x-values), while the range consists of all possible output values (y-values). If you provide more details about the function or its characteristics, I can help you determine the domain and range.
there is no graph... but most chance it's all real numbers
The domain of a function refers to the set of all possible input values (x-values) for which the function is defined. On a graph, the domain is represented along the x-axis, indicating the range of x-values for which the corresponding y-values (outputs) exist. Any gaps or restrictions in the domain, such as undefined points or vertical asymptotes, are visually evident in the graph, where certain x-values do not produce valid outputs. Understanding the domain helps to accurately interpret the behavior and limitations of the function represented in the graph.
The "x values that work are the domain numbers like for y=x+1 would be any real number. But, y= sqrx x would have to be non-negative.
If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
You do not graph range and domain: you can determine the range and domain of a graph. The domain is the set of all the x-values and the range is is the set of all the y-values that are used in the graph.

The practical domain is the domain by simply looking at the function. Whereas the mathematical domain is the domain based on the graph.

Graph each "piece" of the function separately, on the given domain.
