You can put this solution on YOUR website!
if i understand you correctly, you want to solve f(x) = 2*x^2 - 4 when x = 2.
\n" ); document.write( "this becomes f(2) = 2*2^2 - 4
\n" ); document.write( "this becomes f(2) = 4 - 4
\n" ); document.write( "this becomes f(2) = 0
\n" ); document.write( "answer would be f(2) = 0
\n" ); document.write( "if i understand you correctly.
\n" ); document.write( " \n" ); document.write( "
