Since it's a linear function,
\n" ); document.write( " $\"f%28a%2B1%29=f%28a%29%2Bf%281%29\"$
\n" ); document.write( " $\"2f%28a%2B1%29=2f%28a%29%2B2f%281%29\"$
\n" ); document.write( " $\"10=2f%28a%29%2B2%281%29\"$
\n" ); document.write( " $\"2f%28a%29=8\"$
\n" ); document.write( " $\"f%28a%29=4\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"f%282a%29=f%28a%29%2Bf%28a%29\"$
\n" ); document.write( " $\"f%282a%29=4%2B4\"$
\n" ); document.write( " $\"f%282a%29=8\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
