## Solving for Vertical Asymptotes of Rational Functions

You can tell the function graphed above has a vertical asymptote at x=2 as the graph on the left and right sides of x=2 approach negative infinity and positive infinity, respectively. However, how do we determine the vertical asymptote(s) of a rational function without a graph? In order to find a vertical asymptote of a…
