f(x)=(x+3)/(x-4)\r

\n" ); document.write( "\n" ); document.write( "\"f%28x%29=%28x%2B3%29%2F%28x-4%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Vertical asymptote at x=4. Branches of f go in different directions around this asymptote. Notice that for x extreme to left or to right, f approaches but never reaches 1.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Domain: Only EXCLUDED value is x=4.\r
\n" ); document.write( "\n" ); document.write( "Range: The only excluded value for f is at y=1.
