Zubova I.K., Rassokha E.N. APPROACHES TO THE DETERMINATION OF CONVEXITY AND CONCAVITY OF PLOTTED FUNCTION.The authors examined three determinations of the concept of convexity and concavity of plotted function with help of the method of tangents, chords and analytical method. The historical conditions for their formation are shown from the position of the development of differential calculus. The diagram of the account of this theme is offered to the students of physico-mathematical specialties.Key words: the convexity (concavity) of plotted function; the continuity of function; the differentiability of function; tangential straight line; secant straight line; chord.
