You can put this solution on YOUR website!
To find G(-3+h) replace every t you see with (-3+h), we get
\n" ); document.write( " $\"G%28-3%2Bh%29+=+9+-+2%2A%28-3%2Bh%29\"$
\n" ); document.write( "which is
\n" ); document.write( " $\"G%28-3%2Bh%29+=+15+-+2h\"$
\n" ); document.write( "--
\n" ); document.write( "Now, G(-3) means replace very t with -3 and we get
\n" ); document.write( " $\"G%28-3%29+=+9-2%28-3%29\"$
\n" ); document.write( "Which is
\n" ); document.write( " $\"G%28-3%29+=+15\"$
\n" ); document.write( "--
\n" ); document.write( "So,
\n" ); document.write( "G(-3+h) -G(-3) = 15-2h - 15 = -2h \n" ); document.write( "

\n" );
