SUMMARY
This discussion focuses on finding the matrix representation of a linear transformation T with respect to the standard basis for polynomials. The transformation is applied to the basis vectors 1, x, and x^2, resulting in the matrix A = [T]_B = \begin{pmatrix}1 & 3 & 9\\0 & 2 & 12\\0 & 0 & 4\end{pmatrix}. The eigenvalues of this matrix are confirmed as λ₁ = 1, λ₂ = 2, and λ₃ = 4. Additionally, the discussion raises a question about finding the B-coordinates of a polynomial p(x) = ax² + bx + c and how the matrix [T]_B transforms those coordinates.
