Find \( l_{\infty} \) and \( l_{2} \) norms of the vectors. a. \( \mathbf{x}=(2,-2,1)^{t} \) b. \( \mathbf{x}=(-4 / 5,-2 / 5,1 / 5,2 / 5)^{t} \) c. \( \mathbf{x}=((2+k) / k, 1 / \sqrt{k},-3)^{t} \) for a fixed positive integer \( k \) d. \( \mathbf{x}=((3 k+1) /(2 k), 2,0,1 / k)^{t} \) for a fixed positive integer \( k \)
