<h3>How to find the domain of a graph?</h3>
The domain of a function is the set of all possible inputs for the function.
Domain are all the values that go into a function.
The domain of the graph are the values of the x coordinates.
The domain are called the input or independent variables.
The independent variable does not depend on any variable to get it values.
Therefore, the domain of the graph is (0, 20)
