The existence of a Fixed Point is:A) Let g e C[a, b] be such that g(x) = (a, b), In addition, if g' exists on (a, b) and that a constant 0 1 exists withlg'(x)] ? k, for all x = (a, b).then the function g has a unique fixed-point p in [a, b].D) Let g e C(a, b) be such that g(x) = [a, b]. In addition, if g' exists on (a, b) and that a constant k> 1 exists withlg'(x)] s k, for all x € (a, b).then the function g has a unique fixed-point p in [a, b].E)Let g e Cla, b] be such that g(x) e [a, b]. In addition, if g' exists on (a, b) and that a constant 0
