Let f(x) = x^3 + p*x^2 + q*x + r, where p, q and r are natural numbers. If f(0) and f(–1) are both odd, then which of the
following is/are definitely true?

I. f(x) = 0 cannot have any integer roots.
II. f(x) = 0 has three distinct integer roots.
III.Roots of f(x) = 0 are imaginary.

A) Only II B ) I and III C) Only I D) Only III

• its f(-1) not f(ae''1)
