WebWe interpret the matrix as a list of 3 column vectors, each of which is 2-dimensional. The matrix is sending <1, 0, 0> to the left vector, <0, 1, 0> to the middle vector, and <0, 0, 1> to the right vector. Because they're being mapped to 2D vectors, the range of the transformation is ℝ². WebQ: Find the following matrix product, if it exists.
