\[3rd-degree\] Polynomial Word Problem Help

A \[3rd-degree\] polynomial function f(x) has a nonzero constant term and has no variation in sign. consider the following statement:

"f(x) must have at least one negative real number among its zeros."

(a) The statement is True

If you could explain the reasoning behind this it would help a lot! Thanks
