Q. A polynomial function f(x) with integer coefficients has a leading coefficient of 1 and a constant term of −16. According to the Rational Root Theorem, which of the following are possible roots of f(x)?Multi-select Choices:(A) −1(B) −14(C) −54(D) −3
Rational Root Theorem: The Rational Root Theorem states that any rational root, in the form of qp (where p and q are integers and q is not zero), of a polynomial equation with integer coefficients must be a factor of the constant term divided by a factor of the leading coefficient.
Factors of Constant Term: Since the leading coefficient is 1, any rational root must be a factor of the constant term −16. The factors of −16 are ±1, ±2, ±4, ±8, and ±16.
Checking Options: Check each of the given options against the factors of −16.(A) −1 is a factor of −16, so it could be a root.(B) −14 is not a factor of −16, so it cannot be a root.(C) −54 is not an integer and thus cannot be a root since the coefficients are integers.(D) −3 is not a factor of −16, so it cannot be a root.
