non-bracketing using the Secant* method on matlab with the function file

function [y]=fofx(x)

y=x^3+2x^2-111*x+108

end

2. Create a function file that uses the Secand method to solve for the root of the equation from the last assignment. Use the function fofx (again from last assignment) to calculate its value at the needed points. The inputs should be the maximum allowable relative error and the two initial guesses
