Question

Determine whether or not the transformation T is linear. If the transformation is linear, find the associated representation matrix (with respect to the standard basis).

(a) T ( x , y ) = ( y , x + 2 )

(b) T ( x , y ) = ( x + y , 0 )

Answer #1

Give an example of a linear transformation T:R2

explain why: (i) v = 0, (ii) T(v) = 0.
(b) Find the matrix associated to the geometric transformation
on R2 that first reflects over the y-axis and then
contracts in the y-direction by a factor of 1/3 and expands in the
x direction by a...
