Work Step by Step
To sketch a graph of a rational function, you can start by finding the asymptotes and intercepts.
Steps involved in graphing rational functions:
1.Find the asymptotes of the rational function, if any.
2.Draw the asymptotes as dotted lines.
3.Find the $x$-intercept (s) and $y$ -intercept of the rational function, if any.
4.Find the values of $y$ for several different values of $x$.
5.Plot the points and draw a smooth curve to connect the points. Make sure that the graph does not cross the vertical asymptotes.
