Write a polynomial function of least degree with integral coefficients that has the given zeros. -(1/3), -i

Step-by-step explanation:

If a real number is a zero of polynomial function, then

is the factor of this function.

If a complex number is a xero of the polynomial function, then the complex number is also a zero of this function and

are two factors of this function.

So, the function of least degree is

If the polynomial function must be with integer coefficients, then it has a form

-6 is the correct option from the above given options
