(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Not too sure what this proof would be under, but am pretty sure it has to do with approximation errors, can anyone give me a hint as to how to even start this?

2. Relevant equations

3. The attempt at a solution

For the first one, my guess at the solution would be...

1)take the norm of both sides of x = Tx + b

2) then substitute in x^k = Tx^(k-1) + b into the x's

3)since x^k = Tx^(k-1) + b, we get norm( x^k = T(Tx^(k-1) + b) + b), which then we get infinite multiples of T. Hence T^k?

That's really wild guess at the solution, any help would be much appreciated
