You can put this solution on YOUR website!
f(x) = the quantity of 9 x squared plus 9 x minus 18, all over 3 x plus 6\r
\n" ); document.write( "\n" ); document.write( "One may guess that you have \"f%28x%29=%289x%5E2%2B9x-18%29%2F%283x%2B6%29\" which should be simplified.
\n" ); document.write( "\"f%28x%29=%289%2F3%29%28%28x%5E2%2Bx-2%29%2F%28x%2B2%29%29\"

\n" ); document.write( "\n" ); document.write( "This will have a HOLE at x=-2, although seeing it on the graph on the site will be difficult
\n" ); document.write( "or impossible. A zero occurs at x=1. As x goes increasingly large or small (tend toward pos or neg
\n" ); document.write( "infinity), f approaches \"y=3%28x-1%29=3x-3\". Critical values of x are -2 and 1, so the signs in
