4. The following algorithm for approximating roots combines the bisection method with Newton's method and ensures the convergence even in the case where Newton's method fail to converge. Choose an interval [a, b] such that f(a)f(b) ≤ 0. Compute initial approximation xo = (a+b)/2 of the root using the bisection method. For i=1,2,... Compute x₁ using Newton's method and X₁-1. If x₁ [a, b], set x₁ = (a + b)/2 (from bisection). Check for convergence. If f(a) f(xi) ≤0 set b = xi, else set a = xį.
