Using Python:

Derive three different g(x) for finding roots to six decimal places of f(x) = e^x2 +x³ x by Fixed-Point Iteration(FPI). Run FPI for each g(x) and report results, convergence or divergence. f(x) = 0 has three roots. Derive more g(x) if necessary until all roots are found by FPI. For each convergent run, determine the value s from the errors e_i+1/e_i with S determined from calculus.
