By modifying the codes below answer the question

%find root of f(x) = 0

%using Bisection Method

format long e

%chosen error tolerance (TOL)

TOL = .000001;

%choose max number of iterations

MAXIT = 50;

%initial bracket

a = ;

b = ;

%keep track of number of iterations

count = 0;

%record iterates - a col vector of MAXIT length

cits = zeros(MAXIT,1);

%evaluate func. at a and b

fa = fbisect(a);

fb = fbisect(b);

%stop if not appropriate interval

if sign(fa)*sign(fb) >= 0

return

end

%stop loop when error less than TOL or MAXIT reached

while abs(b-a)/2 >= TOL & count

%get midpoint(root estimate)

c = (a + b)/2;

%eval. func at midpoint

fc = fbisect(c);

%stop if f(c)=0

if fc == 0

break

end

%update count

count = count + 1;

%add to list of iterates

cits(count) = c;

%if sign change between a and c make c the new right endpt

if sign(fa)*sign(fc)

b = c;

%if sign chg betw c and b make c the new left endpt

else

a = c;

end

end

%update count

count = count + 1;

%get final midpoint(root estimate)

c = (a+b)/2;

%add to vector of iterates

cits(count) = c;

%display error estimate

error = abs(b-a)/2

%display vector of iterates

cits

%display number of iterates

count

MATLAB Problems: 1) Modify the code bisect.m (provided in eLearning) to write a new script, falpos.m, that performs the Method of False Position. You will only need to add/modify a few lines of code. Run your script to compute approximations to the r coordinates of any intersections of the circle Page 2 of 4 (x-I)' + (y-1)' = 1 and the parabola y = x2. For each intersection, determine an initial bracket of unit length to use in your script. Also, write a separate function m-file, fbisect.m, to compute an appropriate function whose roots you will need to approximate for the x coordinates of the ntersections
