It need not necessarily do so. For example, consider f(x) = 1/(x-2)Suppose you start with x = 5 which gives f(x) = 0.33... and x = -5 which gives f(x) = -0.14286
Bisecting the interval (-5, 5) gives x = 0 and so f(x) = -0.5
which is further away from the previous value.
In the bisection method, the root convergence occurs by repeatedly dividing the interval that contains the root into smaller intervals. In each iteration, the method checks whether the midpoint of the interval is the root or if it lies on one side of the root. The method then selects the subinterval where the root lies and continues to divide it further until the desired level of accuracy is achieved. The convergence is guaranteed because the interval containing the root is halved in each iteration.

What is the Real root of 1-0.6x divided by x using bisection method?
The root of f(x)=(1-0.6x)/x is 1.6666... To see how the bisection method is used please see the related question below (link).
Disadvantages of the bisection method in numerical methods?
The main disadvantage of the bisection method for finding the root of an equation is that, compared to methods like the Newton-Raphson method and the Secant method, it requires a lot of work and a lot of iterations to get an answer with very small error, whilst a quarter of the same amount of work on the N-R method would give an answer with an error just as small.In other words compared to other methods, the bisection method takes a long time to get to a decent answer and this is it's biggest disadvantage.
Numerical method for solving can eqution bisection method?
A root-finding algorithm is a numerical method, or algorithm, for finding a value. Finding a root of f(x) − g(x) = 0 is the same as solving the equation f(x) = g(x).

What are the advantages and disadvantages of the bisection method compare with that of the linear interpolation method?
The bisection method is simpler to implement and guarantees convergence to a root if one exists within the initial interval, but it can be slower as it always halves the interval. In contrast, linear interpolation converges faster but does not guarantee convergence, and it might fail if the function is not well approximated by a linear model in the interval.
How do you find the The initial range of Bisection method?
If this is in the context of finding a root of an equation, the answer is to make some guesses. Find value x1 and x2 such that f(x1) and f(x2) have opposite signs. Then, provided that f is a continuous function over (x1, x2), the bisection method will find its root.

Why it is advantageous to combine Newton Raphson method and Bisection method to find the root of an algebraic equation of single variable?
An improved root finding scheme is to combine the bisection and Newton-Raphson methods. The bisection method guarantees a root (or singularity) and is used to limit the changes in position estimated by the Newton-Raphson method when the linear assumption is poor. However, Newton-Raphson steps are taken in the nearly linear regime to speed convergence. In other words, if we know that we have a root bracketed between our two bounding points, we first consider the Newton-Raphson step. If that would predict a next point that is outside of our bracketed range, then we do a bisection step instead by choosing the midpoint of the range to be the next point. We then evaluate the function at the next point and, depending on the sign of that evaluation, replace one of the bounding points with the new point. This keeps the root bracketed, while allowing us to benefit from the speed of Newton-Raphson.

To find the roots of 2xx-5x plus 1 equals 0 by bisection method?
I'm not familiar with the "bisection method" to find the roots of 2x2-5x+1 = 0 but by completing the square or using the quadratic equation formula you'll find that the solution is: x = (5 + or - the square root of 17) over 4 Hope that helps.

What is the rate of convergence for the bisection method?
The rate of convergance for the bisection method is the same as it is for every other iteration method, please see the related question for more info. The actual specific 'rate' depends entirely on what your iteration equation is and will vary from problem to problem. As for the order of convergance for the bisection method, if I remember correctly it has linear convergence i.e. the convergence is of order 1. Anyway, please see the related question.
