3. For each of the following inner product spaces V and linear operators T on V, evaluate T* at the given vector in V. (a) VR2, T(a, b) = (2a + b, a 3b), x = (3, 5). (b) V = C², T(21, 22) = (221 + iz2, (1 − i)z1), x = (3 — i, 1 + 2i). - (c) V=P₁(R) with (f,g) = {* f(t)g(t) dt, T(f) = ƒ' +3f, f(t)=4-2t
