If f(x)= 4x-2, then f(x+h)-f(x)=
\n" ); document.write( ".
\n" ); document.write( "Plug in the given values:
\n" ); document.write( "f(x+h) = 4(x+h) - 2
\n" ); document.write( "and, of course:
\n" ); document.write( "f(x) = 4x -2
\n" ); document.write( ".
\n" ); document.write( "So,
\n" ); document.write( "f(x+h)-f(x)= 4(x+h) - 2 - (4x -2)
\n" ); document.write( "f(x+h)-f(x)= 4x+4h-2 - (4x -2)
\n" ); document.write( "f(x+h)-f(x)= 4x+4h-2 -4x+2
\n" ); document.write( "f(x+h)-f(x)= 4x+4h-4x
\n" ); document.write( "f(x+h)-f(x)= 4h\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
