f(2,1) = (2,1)
Either explain why f is not linear or write down the matrix that represents f .
iI general how do you solve problems of this type?
This equation is of the form AX = L X
where L is the eigen value corresponds to the matrix A with respect to the characteristic matrix X
And this corresponds to a linear transformation. ...
This shows how to explain why a transformation is not linear or write the matrix that represents the transformation.
