We are interested in the real-valued zeros for f(x) = x² - 2 within the interval [0,2]. (a) Perform two steps of the bisection method and provide the boundaries of the reduced interval, in which the zero must be located. (b) Use Newton's iteration method and perform one step. As a start value use xo = 1.0. (c) Rewrite the above search for zeros as a fixed-point iteration problem. Is there a guarantee that the iterative sequence converges to a fixed-point if one chooses an arbitrary start value out of the interval [0,2]? Justify your answer with a calculation.
