(a) Prove that f is a linear map. (b) Find a matrix representation for f using
the basis of polynomials {1, x, x², x³} for the input space and for the output
space.
2. Let f : R³ → R³ be the function in which f(v) is the result of first
projecting v orthogonally onto the plane 3r – 4y+12z = 0 and then rotating
the resulting vector 45° in that plane counter-clockwise with respect to the
direction vector
