Final answer:
The rational function age can be written as [(x - a)(x - b)(x - c)] / {-(x - d)^3} where a, b, c are the zeros of the polynomial p with multiplicity of one and d is the zero of the polynomial q with multiplicity of three.
Step-by-step explanation:
A polynomial function with three distinct zeros, each with a multiplicity of one, and a positive leading coefficient can be written in the form p(x) = (x - a)(x - b)(x - c), where a, b, and c are the zeros. A polynomial function with one zero of multiplicity three and a negative leading coefficient can be written in the form q(x) = -(x - d)^3, where d is the zero. To express the rational function age(x) = p(x) / q(x) as the quotient of these two polynomial functions, we replace p(x) and q(x) with their respective forms, resulting in age(x) = [(x - a)(x - b)(x - c)] / {-(x - d)^3}.
