Graphs of functions y = f(x) and y = 2y_{0}  f(x) are symmetrical relatively to a horizontal line y= y_{0}. In case of degeneracy of y_{0}=0 the graphs are axis OX reflected. Graphs of functions y = f(x) and y = f(2x_{0}  x) are symmetrically relatively a vertical line x= x_{0}. In case of degeneracy of x_{0}=0 the graphs are axis OY reflected. These are axial symmetry. Graphs of functions y = f(x) and y = 2 y_{0}  f(2 x_{0}  x) are symmetrically relatively to a point (a; b). In case of degeneracy of x_{0}=0 and y_{0}=0 the graphs are the point of origin reflected. The simulation allows a user to enter a function f(x), set x_{0} and y_{0}. Press a button with a reflection function and obtain a graph transformation.
