$\"f%282%29=2t%5E2-4t-1\"$ Start with the given function.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%282%29=2%282%29%5E2-4%282%29-1\"$ Plug in $\"t=2\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%282%29=2%284%29-4%282%29-1\"$ Square $\"2\"$ to get $\"4\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%282%29=8-4%282%29-1\"$ Multiply $\"2\"$ and $\"4\"$ to get $\"8\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%282%29=8-8-1\"$ Multiply $\"-4\"$ and $\"2\"$ to get $\"-8\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%282%29=-1\"$ Combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the answer is $\"f%282%29=-1\"$ \n" ); document.write( "

\n" );
