Can anone here explain to me how to find the computational complexity of Newtons Method for roots?

I think you could start with the simplest features first, and then slowly introduce more complex features... (gradient should tell you what is useful and what isn't..)
Eg. for y=2x + 2, start with the bias, and the gradient will go up above +2, then if you add in the x^1 term, bias will drop down to 2 and x^1 will also go to 2... (this is a perfect fit), so then if you try to add in x^2, the weight should stay at (or very near) 0, because adding weight to this term will make the hypothesis worse...
