review text: The author continues his research in constructing linear methods for approximating functions by parabolic splines with equidistant knots, inheriting such properties of approximated functions as monotony and convexity. The obtained results are generalized to the case of nonequidistant knots and to some kinds of exponential splines of the third order.
