Problem 8. Determine which of the following are linear maps. Prove your answers. (a) T₁ : R² → R2 defined by T(x, y) = (2x − y, x+y). (b) T₂: R² → R² defined by T(x, y) = (0, xy). (c) T3 : P(R) → R defined by T3(p) = |p'(0)|. (d) T₁ : R³ → P2 (R) defined by [T₁(a, b, c)](x) = a +bx+cx² for all x E R.
