In this lesson you began to explore the graphs of rational functions. Making a table of values, using technology, or using transformations can be good strategies for graphing rational functions. Be careful when using transformations, as some rational functions are hard to interpret this way.
Many rational functions have non-permissible values. Sometimes these will show up as asymptotes on graphs. In the next lesson you will explore when asymptotes and holes, another type of discontinuity, occur in rational graphs.
