Best ResponseYou've already chosen the best response.1I think you need to apply the transformation to each vector of the basis.

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

Best ResponseYou've already chosen the best response.0So would the first vector in the basis for f1 be [1,0,2] because of the standard basis [1,x,x^2]?

Best ResponseYou've already chosen the best response.1I thought that is the way, but I'm checking. if its true.

Best ResponseYou've already chosen the best response.1Hmm what is the result of apply the transformation to the f_1 vector?

Best ResponseYou've already chosen the best response.1\[T(f_1(t)) = f_1(2t+1)=1+2(2t+1)^2\]

Best ResponseYou've already chosen the best response.1I got \(3 + 8t + 8t^2\) am I right?

Best ResponseYou've already chosen the best response.0sec... I think there's something more you have to do. Let me pull up some pages from a book.

Best ResponseYou've already chosen the best response.0So it looks like you first have to plug 2t+1 into the x's in your standard P2 polynomial first.

Best ResponseYou've already chosen the best response.0So you'll have 4t^2+4t+1

Best ResponseYou've already chosen the best response.1what is your standard polynomial?

brinethery

Best ResponseYou've already chosen the best response.0I 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

Best ResponseYou've already chosen the best response.0See 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.

Best ResponseYou've already chosen the best response.1You need to remember how to obtain the matrix of a transformation first.

Best ResponseYou've already chosen the best response.1Right 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.

Best ResponseYou've already chosen the best response.0I'm fine, I just really need help to this question

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

Best ResponseYou've already chosen the best response.1with the results aligned in columns.

Best ResponseYou've already chosen the best response.1I mean: \[\left[\begin{matrix} F^T(f_1(t))& F^T(f_2(t)) & F^T(f_3(t)) &\end{matrix}\right]\]
