A graph of . The two points and lie on this graph. The normals at and intersect at the point . Find the points and on the graph of the inverse
If P= is on then we must have so either p= 0 or , . If it were on , then we would have to have which is only true for p= 0. Since R is not given I see no information derived from "the normals at P and Q intersect at R" except that they do intersect and are not parallel. The only way I could make any sense out of this is to say that P= Q= (0,0).
