Please, help me! I have the coordinates of the curve y = [150 150 130 130 130 100 100 100 80 80 80 60], x = [52000 70000 74000 96000 100000 170000 220000 245000 530000 720000 810000 4900000]. This curve well described by power function. How can I build the same curve passing through the point A(68856, 210) and get it equation?
