In this paper, sufficient conditions have been obtained under which every solution of$[y(t)?± y(t-e???)]'?±mathcal{Q}(t)G(y(t-e???)) = f(t),quad ta‰￥ 0$,oscillates or tends to zero or to ?± a?? as e?‘? a?’ a??. Usually these conditions are stronger thanegin{equation*}intlimits_0^a??mathcal{Q}(t)dt=a??. ag{*}end{equation*}An example is given to show that the condition $(*)$ is not enough to arrive at the above conclusion. Existence of a positive (or negative) solution of$[y(t)-y(t-e???)]'+mathcal{Q}(t)G(y(t-e???))=f(t)$is considered.
