Symmetry can be useful in graphing an equation since it says that if we know one portion of the graph then we will also know the remaining (and symmetric) portion of the graph as well. We used this fact when we were graphing parabolas to get an extra point of some of the graphs. In this section we want to look at three types of symmetry. 10.1 Graph Rational Functions Graph the following and write the equations of the horizontal asymptote and vertical asymptote. ...
