4. Let a = (-5, 3,-2), and consider the linear transformation: E : P³ → R³. Compute Ea(7x³ – 4x² + 3x – 6) Find a basis for ker(Ea). Hint: think of a factored form for p(x) if E¿(p(x)) = z(x). а. b. 4. Let a = (-5, 3,-2), and consider the linear transformation: E : P³ → R³. Compute Ea(7x³ – 4x² + 3x – 6) Find a basis for ker(Ea).
