The operation is a closed system under subtraction because subtracting two polynomials results in another polynomial, preserving the structure of polynomial functions. Specifically, in this case, subtracting \((2x^2 + 12x + 11)\) from \((9x^2 + 17x + 13)\) yields a new polynomial, which remains within the set of polynomials.
