2x^2 -3, find [f(x+h)-f(x)]/h
\n" ); document.write( "-------------------
\n" ); document.write( "f(x+h) = 2(x+h)^2-3
\n" ); document.write( "f(x+h) = 2x^2 + 4hx + 2h^2 - 3
\n" ); document.write( "f(x) = 2x^2 - 3
\n" ); document.write( "-----
\n" ); document.write( "Subtracting you get::
\n" ); document.write( "4hx + 2h^2
\n" ); document.write( "----
\n" ); document.write( "Dividing by h you get:
\n" ); document.write( "4x + 2h
\n" ); document.write( "-------------------
