![]() ![]() Identify the intervals to be included in the set by determining where the heavy line overlays the real line.6 Natural domain of a function With the expressions likex or1/x, we saw how the domain of a functionmay be restricted by a formula from which we compute its values. What is the domain of the function defined by the graph above Answer. Given a line graph, describe the set of values using interval notation. In other words, the domain is the projection of the graph on thex-axis. The range is the set of outputs that the system or function will produce when given the. A square bracket indicates inclusion in the set, and a parenthesis indicates exclusion from the set. Put simply, the domain represents the inputs to a system or a function. The endpoint values are listed between brackets or parentheses. Interval notation is a way of describing sets that include all real numbers between a lower limit that may or may not be included and an upper limit that may or may not be included. ![]() The range of a function is the set of all output values (Y-values). In other words, the domain is the set of values that we can plug into a function. The domain of a function is the set of all acceptable input values (X-values). \) which is read as, “the set of all x such that the statement about x is true.” For example, The range of a function is all the possible values of the dependent variable y.
