摘要：
The paper continues investigations of the well-known class T of typically real functions f(z) in the disk U = {z:|z| < 1}. The region of values of the system {c2, c3, f(z1), f(z2)} in the class T is studied. The region of values of f(z2) in the class of functions f ∈ T with fixed values c2, c3, and f(z1) is determined. Bibliography: 9 titles.
