refer to the function f(x)=3x^3-11x^2+5x+3
\n" ); document.write( "HERE THERE ARE 2 SIGN CHANGES IN F(X)...
\n" ); document.write( "1..FROM 3 TO -11
\n" ); document.write( "2.FROM -11 TO +5
\n" ); document.write( "SO THERE COULD BE 2 OR 0 POSITIVE ROOTS AS PER THE RULE OF SIGNS
\n" ); document.write( "Use DesCartes' rule of signs to determine the possible number of positive real zeros
\n" ); document.write( "a. 4 or 2 or 0
\n" ); document.write( "b. 2 or 0.....................OK
\n" ); document.write( "c. 3 or 1
\n" ); document.write( "d. 3 or 1 or 0
\n" ); document.write( "e. none of these
\n" ); document.write( "
\n" ); document.write( "
\n" );
