### Concept (1)

: The graph of a basic rational function (1/x) is easy to do by plotting key points. When **graphing rational functions**, the functions are asymptotic to either the x-axis and y-axis or to certain lines if there are shifts in the graphs. More complex graphs of rational functions include functions with graph shifts.
