None of these are true
\n" ); document.write( "*******************************************************
\n" ); document.write( "a or b can be absolute max or absolute min on [a, b]
\n" ); document.write( "the first derivative is the tool we use to find inflection points
\n" ); document.write( "if second derivative < 0 then we have concave down
\n" ); document.write( "
\n" ); document.write( "
\n" );
