find the vertical asymtotes, f any, of the graph of the rational function.
\n" ); document.write( "f(x)=x/x^2+4
\n" ); document.write( "--------------
\n" ); document.write( "You have possible vertical asymptotes when the denominator is zero.
\n" ); document.write( "----------
\n" ); document.write( "So, solve x^2+4 = 0
\n" ); document.write( "x^2 = -4
\n" ); document.write( "x = +-2i and is not a Real Number.
\n" ); document.write( "-------------
\n" ); document.write( "So f has no vertical asymptotes
\n" ); document.write( "=======================
