Please give a written description for the questions. The code that part A and part B are referring to is given.

function root recur bisec (f, a, b, eps) % finds the mid value (a+b)/2; m = % if tolerence is reached then return the mas root if(abs (f (m)) 0 replace a by m and call recursively elseif(f(m)>0) root = recur bisec (f,m,b,eps); 9 10 ?1 22 > 3 end -end This is the question being asked: Describe how you would use your Matlab functions from #1 to find all of the roots of a given function f on a given interval (a, b) cR to a given error tolerance E ER, provided that you are given a plot on paper of the function values over the interval. Describe how you would use your Matlab function from #1 to find all of the roots of a given function f on a given interval (a, b) c R to a given error tolerance E R if you know nothing in advance about the function values over the interval
