Abstract: In this article the authors established sufficient condition for the first order delay differential equation in the form x(t) + p(t)x(r(t)) = 0, t ≥t0, (*) where r(t) < t , limt→∞ r(t) = ∞ and p(t) is a non negative piecewise continuous function. Some interesting examples are provided to illustrate the results.
