Trevor is studying a polynomial function f of x Three given roots of f of x are negative 7 , 2 i , and 7 Trevor concludes that f of x must be a polynomial with degree 3 Which statement is true?

Trevor is correct.

Trevor is not correct because negative 2 i must also be a root.

Trevor is not correct because there cannot be both rational and complex roots.

Trevor is not correct because there cannot be an odd number of roots.
