\n" ); document.write( "\n" ); document.write( "Let's evaluate $\"f%28-1%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%28x%29=2x%2B2\"$ Start with the given function.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%28-1%29=2%28-1%29%2B2\"$ Plug in $\"x=-1\"$ . In other words, replace each x with -1.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%28-1%29=-2%2B2\"$ Multiply 2 and -1 to get -2\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%28-1%29=0\"$ Now combine like terms
\n" ); document.write( " \n" ); document.write( "
