You can put this solution on YOUR website!
The function description is a bit ambiguous. Maybe you have $\"f%28x%29=%284x%5E2-4x-8%29%2F%282x%2B2%29\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%282x%5E2-2x-4%29%2F%28x%2B2%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Vertical asymptote for x=-2 and slant asymptote $\"y=2x-2\"$ , based on polynomial division. You can check for roots, for x^2-x-2=(x+1)(x-2). The roots are x=-1 and x=2. That might be enough to pick the correct graph of your choices.\r

\n" ); document.write( "Yes, this can appear to be the same as a line, but you must understand there IS an undefined point for the function which may not show on this graph here; it is a hole. \n" ); document.write( "
