Since {x_n} converges, prove (d. We also know |f'(x)| <=  1/3. 

(a) Prove that for any a, b e R,
| f(a) – f(b)|
а - b
(b) Define a sequence by rn = f(xn-1) starting at some fixed ro E R. Prove
|In+1 – In| <|Tn – Tn-1|-
(c) Prove that {Tn} converges in R.
(d) Prove that there exists a E R such that f(a) = a.
