Kernel and Transformation Concepts

The video tutorial explains a transformation from M22 to R3, defined by a specific matrix operation. It covers how to find a basis for the image or range of the transformation by expressing output vectors as linear combinations. The tutorial also details finding a basis for the kernel, focusing on input matrices that result in a zero vector output. The process involves breaking down matrices into linear combinations of simpler matrices.

What is the transformation T from M22 to R3 defined as?

• T of the 2x2 matrix abcd equals the vector a, b, c

• T of the 2x2 matrix abcd equals the vector a-b, a, a+b

• T of the 2x2 matrix abcd equals the vector a+b, a, a-b

• T of the 2x2 matrix abcd equals the vector b, a, d
