kindly answer it
![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(f)] (n) = ⋅
{(₁-1)
n = 1
f(n-1) n ≥2
Determine ker(L) and im(L).
Note: One of these is finite dimensional. A good exercise would be to find a basis for
that subspace, but we won't ask you to do that in this question.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6d313e15-ae9d-4d9a-951d-e3eb75f01033%2F9915b2fd-09f7-4706-8a22-1ad570791f6f%2Fcdgqnki_processed.png&w=3840&q=75)
