Domain and Range of a Function From a Graph

This precalculus video tutorial explains how to find the domain and range of a function given its graph in interval notation. The domain represents all of the x values in the function and the range represents all of the y values. You should use parentheses for open circles and infinity symbols but you should brackets for closed circles. This video contains plenty of examples and practice problems of finding the domain and range of a graph.
