Let F be a field and let V, be the F-vector space of polynomials in F[x] of degree <n. Which of the
following maps are linear transformations?
(a) The map D : n → Vn-1 sending p(x) to p'(x) = P(x).
(b) The map I : Vn → Vn+1 sending p(x) to P(x) := * p(t)dt.
(c) The map sending p(x) to p(x)².
(d) The map sending p(x) to p(x + 1) – p(x).
(e) The map sending p(x) to p(x)p(x – 1).
Provide a brief explanation -- ideally not more than one or two complete sentences -- for each of your
answers.
