Question: a. Prove that ||x (k) x|| ||T|| k ||x (0) x|| and ||x (k) x|| ||T|| k /1 ||T||

a. Prove that ||x^(k) − x|| ≤ ||T||^k ||x⁽⁰⁾ − x|| and ||x^(k) − x|| ≤ ||T||^k /1 − ||T|| ||x⁽¹⁾ − x⁽⁰⁾ ||, Where T is an n × n matrix with ||T|| < 1 and x^(k) = Tx^(k−1) + c, k = 1, 2, . . . , With x⁽⁰⁾ arbitrary, c ∈ Rⁿ, and x = Tx + c.

b. Apply the bounds to Exercise 1, when possible, using the l∞ norm.
