Hi, I'm not sure whether this is a suitable problem for this section. Anyway, I have a set of points and I need to find a polynomial. The points are.. (0,3),(1,10),(2,10),(3,10)....(50,10) how do I get the polynomial?

yeah.. but I need to find the value at x = -1. In that y = 10 is not the perfect fir.

Originally Posted by FernandoRevilla If you mean the polynomial passing through those points, look here: Lagrange polynomial Yes. I need the one through the points. But the resulting polynomial will be of degree 50. Am I right? Is that the simplest that I can get? Thank you for your suggestion!
You can express where
