Write a MATLAB script to solve for the root of the (analytically solvable) exponential decay formula: 8.51e0.56x=4.71 Using the secant method, with initial values of x1=0.8 and x2=9.6, and assuming you were printing out each iteration in the form: i,xi2,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, what is the value of x9 ? Your answer must match the value to within 0.0001. If the method diverges (divides by zero), enter 999
