Question
Assume that T is a linear transformation. Find the standard matrix of T.

Transcribed Image Text:Let \( T : \mathbb{R}^3 \rightarrow \mathbb{R}^2 \) be a linear transformation defined by its action on the standard basis vectors. The transformation is given by:
- \( T(e_1) = (1, 3) \)
- \( T(e_2) = (4, 2) \)
- \( T(e_3) = (-5, 4) \)
where \( e_1 \), \( e_2 \), and \( e_3 \) are the columns of the \( 3 \times 3 \) identity matrix.
This linear transformation maps vectors from a three-dimensional space (\( \mathbb{R}^3 \)) to a two-dimensional space (\( \mathbb{R}^2 \)). The vectors \( e_1 \), \( e_2 \), and \( e_3 \) are the standard basis vectors in \( \mathbb{R}^3 \).
