Summary.Let λ > 1 and $$a \in {\mathbb{R}}, a \neq 0$$ . We give a method to construct solutions for the initial value problem of the functional-differential equation f′(x) = af(λ x) for $$x\in {\mathbb{R}}$$ and the initial condition f(0) = 0. Several authors studied relevant equations. Our method is different from all of them and gives numerical data readily. We give graphs of several solutions...
