Solving Nonlinear Equation (Newton Raphson Algorithm)

Please help me solve the following question in Matlab:

Write a Matlab code which uses Newton Raphson Method to compute an approximate solution to the equation f(x)=0 starting from xo and stopping when the magnitude of f(x) becomes smaller than e. The program should restrict the maximum number of iteration to N.
