Which of the following are advantages of bracketing methods

Which of the following are advantages of bracketing methods in general? Select one: a. They have quadratic convergence b. They require only one initial guess c. They are generally faster than open methods d. They (nearly) always converge

Solution

Solutions:

The correct option would be d.

Bracketing method always converge. This is because it is one of the closed method and the approximation is done very perfectly to get the convergence.
