Example \(\PageIndex{6B}\): Finding Domain and Range from a Graph of Oil Production. ]. However, because absolute value is defined as a distance from 0, the output can only be greater than or equal to 0. For the quadratic function [latex]f\left(x\right)={x}^{2}[/latex], the domain is all real numbers since the horizontal extent of the graph is the whole real number line. x2 is different from the domain of f(x)={ x=1 Because the graph does not include any negative values for the range, the range is only nonnegative real numbers. In the previous examples, we used inequalities and lists to describe the domain of functions. )=0, Can a functions domain and range be the same? x+1 f(4). Notice that we can use the data to create a function of the amount each movie earned or the total ticket sales for all horror movies by year. At the endpoints of the domain, we draw open circles to indicate where the endpoint is not included because of a less-than or greater-than inequality; we draw a closed circle where the endpoint is included because of a less-than-or-equal-to or greater-than-or-equal-to inequality. Since there is an even root, exclude any real numbers that result in a negative number in the radicand. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values. Parentheses, \((\) or \()\), are used to signify that an endpoint is not included, called exclusive. The function is represented in Figure 24.
