Problem Statement
Given a set of points in the plane, it is called the distance of a point from the plane to the set at the smallest of the distances from to each of the points of . Let the sets be , with and ; and with and , in an orthogonal reference system. Find and draw the set of points in the plane that are equidistant from and . Study whether the function whose graph is the set previously obtained is derivable.
