Given a finite set of points
in the plane (with distinct x coordinates) must there exist a polynomial of degree n
that passes through exactly n + 1 of the points? Provided that the points do not all
lie on the graph of a polynomial of degree n then the answer to this question is yes.
This generalization of Sylvester’s Problem (the n = 1 case) is established as a
corollary to a version of Sylvester’s Problem that holds for certain finite dimensional
Haar spaces of continuous functions.
