\n" ); document.write( "f(-x); f(x)= 3x^2 + 3x - 3
\n" ); document.write( "------------
\n" ); document.write( "Sub -x for x
\n" ); document.write( "---
\n" ); document.write( "f(-x) = 3(-x)^2 + 3(-x) - 3
\n" ); document.write( "= 3x^2 - 3x - 3
\n" ); document.write( "======================
\n" ); document.write( "It's simple substitution.
