I think you need to apply the transformation to each vector of the basis.

Nodata Group TitleBest ResponseYou've already chosen the best response.1
and you form a matrix with the coefficients of the result in columns.

So would the first vector in the basis for f1 be [1,0,2] because of the standard basis [1,x,x^2]?

I thought that is the way, but I'm checking. if its true.

Hmm what is the result of apply the transformation to the f_1 vector?

\[T(f_1(t)) = f_1(2t+1)=1+2(2t+1)^2\]

I got \(3 + 8t + 8t^2\) am I right?

sec... I think there's something more you have to do. Let me pull up some pages from a book.

So it looks like you first have to plug 2t+1 into the x's in your standard P2 polynomial first.

So you'll have 4t^2+4t+1

Nodata Group TitleBest ResponseYou've already chosen the best response.1
what is your standard polynomial?
 2 years ago

brinethery Group TitleBest ResponseYou've already chosen the best response.0
I guess I meant plug in 1 +2t^2 into our polynomial. 4(1+2t^2)^2 +4t +1 = 4(1+2t^2)(1+2t^2) +4t +1 =4(1 + 4t^2 +4t^4) +4t +1

See I'm really confused. I think I'm going to stop right there b/c I'm not on the right track I don't think.

You need to remember how to obtain the matrix of a transformation first.

Always go back to your definitions and well understood theorems brinethery.

Right now I don't remember well, and I don't have math books at work to help you as I wish. But I think that is the way.

How are you?

Nodata Group TitleBest ResponseYou've already chosen the best response.1
As I said you before, you just need to apply the transformation to each of the vectors of your basis. and form a matrix.

I mean: \[\left[\begin{matrix} F^T(f_1(t))& F^T(f_2(t)) & F^T(f_3(t)) &\end{matrix}\right]\]
