The Newton-Raphson Method is a better version of the Fixed Point Interation Method, increasing the speed of the convergence to find the root of the equation. The NRM uses divisions, so it can give a indefinite math error, once the denominator is zero. The formula of the NMR is: x = x0 -(f(x0)/f'(x0)). It is my first MATLAB code. After getting the number of iterations and the root itself, the code plots a graph to show the root, highlighted. Tell me what you like, what you would do it different, and help me get better at MATLAB.

Forgot to change the language of all the code. Where it was "Aproximação Inicial", now is "Initial Aprox."
