You can put this solution on YOUR website!
f(x)=1/x, find f(2+h)-f(2)/h\r
\n" ); document.write( "\n" ); document.write( "f(2+h)-f(2)/h
\n" ); document.write( "=1/(2+h)-[(1/2h)]
\n" ); document.write( "[using f(x) = 1/x and f(2)/h means f(2)X(1/h) = (1/2)X(1/h)=1/(2h)]
\n" ); document.write( "= [2h-(2+h)]/[(2+h)(2h)]
\n" ); document.write( "=[2h-2-h]/2h(2+h)
\n" ); document.write( "=(2h-h-2)/2h(2+h)
\n" ); document.write( "=(h-2)/2h(2+h)
\n" ); document.write( " \n" ); document.write( "

\n" );
