Log On
The function is degree 3 with negative leading coefficient, so the function value is positive for large negative values of x and negative for large positive values of x.
The function has single roots at x=-2, x=1, and x=3; so the sign of the function changes at those values of x. So the function value is...
positive on (-infinity, -2)
negative on (-2,1)
positive on (1,3)
negative on (3,infinity)
