To identify the domain of a function, or the set of all inputs, look at the x-values of the graph.
For example, take a look at the graph of the function f(x). You can tell that 1 is in the
domain of f(x) because there is an ordered pair on the graph with 1 as an x-
coordinate.
In 10 words or fewer, what other numbers do you think are in the
domain of this function?
