Let V = {f: N→ R} endowed with the usual notions of pointwise addition and scalar mul- tiplication. Define two linear operators, R, L: V → V by [L(f)] (n) = f(n+1) and [R(ƒ)](n) = - { n = 1 f(n-1) n≥2 You do not need to prove that these are linear. Compute Lo R: V→V and ROL: V→V. Which of these is the identity operator? Are L and R inverses of one another?
