= { [ * ] | ² ≥ 6 } Consider W = (a) Determine whether W is closed under addition, is closed under scalar multiplication, is a subspace of M2x2. Justify your answer in details. (b) If we change the condition to z ≤ 6, do you think any of the answers in part (a) will change? Justify your answer in details.
