摘要：

A planar mapping was derived from a second order delay differential equation with a piecewise constant argument. Invariant curves for the planar mapping reflects on the dynamics of the differential equation. Results were reported on a planar mapping admitting quadratic invariant curves y=x(2)+C, except for the case -3/4 less than or equal to C<0. This remaining case is now resolved, and we describe the solutions of the functional equation k(x(2) + C) + k(x) = x by iterations of y.
