COSTAS EFTHIMIOU Department of Physics UNIVERSITY OF CENTRAL FLORIDA. The finite-dimensional calculus leads to a system of algebraic equations for the critical points; the infinite-dimensional functional analog results a boundary value prob-lem for a nonlinear ordinary or partial differential equation whose solutions are the critical functions for the variational problem. What are functional equations? The method is based on iterative, In this paper we study the polynomial functional equations of the form $a f(a_1 x +a_0) +b f(b_1 x +b_0)=g(x)$,where  g(x) is a polynomial of the degree $n \geq  0$.
