PLEASE USE MATLAB!!!

Use bisection.m below

function [xn,steps,error] = bisection(f,a,b,tol)

%function returns an estimate for the root, xn, and requires %inputs of the function, g, the interval endpoints, a and b, %the desired tolerance for the error, tol.

error=b-a; %initialize error steps=0; %initialize step counter while error>tol steps=steps+1; %increment counter xn=(a+b)/2; %calculate xn, the midpoint of a and b if f(a)==0 || f(b)==0 %check f(a) and f(b) disp('endpoint is root!') if f(a)==0 xn=a; else xn=b; end break %If f(a or b) = 0 then landed on root and stop iterati elseif f(xn)*f(a) 0 then root is between xn and b, and xn becomes new a end error=b-a; %calculate new error end

Record: 1. your starting interval [, ], and 2. how many iterations it took you to reach .
