Using the Lagrange method to find the polynomial that interpolates the points: f(x) | -3 | -2 | -1 | 0 | 1 | x | -197 | -35 | -1 | 1 | 5 | I find: So I got the following polynomial: Is this correct what I did?

I would say no, because your Can you show all your intermediate steps?
Are you sure you don't have "x" and "f(x)" reversed?

Using Newton's interpolation I find: It seems more reasonable. But the method of Lagrange I could not.
You need to show your work. If you don't do that, we can't help you very much. Here's a page on the Lagrange Interpolating Polynomial.

Ok, have a good one.
