Question

what is the function y2 of the cubic complex function in the general form of y_1=(x-c)(x-(a+ib))(x-(a-ib))? the zeros of y_2 are c, a+b and a-b, it shares 2 points with y1 and is of opposite concavity. thanks!!

Answer 1

what is a shadow function??

Answer 2

\[y_1=(x-c)(x^2-2ax+a^2+b^2)\] if that helps any y
