then 2 is a fixed point of f, because f(2) = 2. Not all functions have fixed points: for example, if f is a function defined on the real numbers as f(x) = x + 1, then it has no fixed points, since x is never equal to x + 1 for any real number. In graphica...

I think you simply don't have a situation in which the iterative algorithm is applicable. See here for some conditions. Your function doesn't have an attractive fixed point near 1.5, and the algorithm diverges. But why the numerics: Your function is f(x) ...

FIXED POINT ITERATION METHOD Fixed point: A point, say, s is called a fixed point if it satisfies the equation x = g(x). Fixed point Iteration: The transcendental equation f(x) = 0 can be converted algebraically into the form x = g(x) and then using the i...
