Write a MATLAB script to solve for the root of the (analytically solvable) exponential decay formula: 3.99e2.14x=2.18. Using the Newton-Raphson method, with an initial value of x0=3.4, and assuming you were printing out each iteration in the form: i,xi1,xi,f(xi) where i is the iteration number, xi is the next guess of the value of the root, and f(x) is defined such that f(x)=0 at the root, at what iteration number i will the value of the root have converged to within (xixi1)108 ? If the method diverges (divides by zero) or has not converged within 1000 iterations, enter -999
