$\"f%28x%29=x%5E2%2B5x%2B7\"$ Start with the given function.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%284%29=%284%29%5E2%2B5%284%29%2B7\"$ Plug in $\"x=4\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%284%29=1%2816%29%2B5%284%29%2B7\"$ Square $\"4\"$ to get $\"16\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%284%29=16%2B5%284%29%2B7\"$ Multiply $\"1\"$ and $\"16\"$ to get $\"16\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%284%29=16%2B20%2B7\"$ Multiply $\"5\"$ and $\"4\"$ to get $\"20\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"f%284%29=43\"$ Combine like terms.
