Write function defined as: def function(fcn, x0, x1, maxiter-10, xtol-1e-5): that use the fsolve to find the root of the callback fcn(x), in the neighborhood of x0 and x1. fcn: the callback function for which we want to find the root (see the specific functions below). x0 and x1: two x values in the neighborhood of the root xtol: exit if the Ixnewest - xprevious] < xtol maxiter: exit if the number of iterations (new x values) equals this number return value: the final estimate of the root (most recent new x value) Write and call main() function that uses your fsolve function to estimate and print the solution of: ; with x0=1, x1= 2, maxiter = 5 and xtol = 1e-4 ; with x0=1, x1= 2, maxiter = 15 and xtol = 1e-8 with x0=1, x1= 2, maxiter = 3 and xtol = 1e-8
