Q. A polynomial function f(x) with integer coefficients has a leading coefficient of 1 and a constant term of −14. According to the Rational Root Theorem, which of the following are possible roots of f(x)?Multi-select Choices:(A) −7(B) 27(C) 14(D) −14
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=0), of a polynomial equation with integer coefficients is such that p is a factor of the constant term and q is a factor of the leading coefficient.
Leading Coefficient: Since the leading coefficient is 1, any rational root will have a denominator of 1, meaning it must be an integer.
Factors of Constant Term: List the factors of the constant term −14: ±1, ±2, ±7, ±14.
Checking Potential Roots: Check each option against the list of factors:(A) −7 is a factor of −14, so it could be a root.(B) 27 is not an integer, so it cannot be a root.(C) 14 is a factor of −14, so it could be a root.(D) −14 is a factor of −14, so it could be a root.
