(a) Apply the Newton-Raphson method to the function f(x) = tanh(x2 - 9) to evaluate its known real root at x = 3. Use an initial guess of x0 = 3.2 and take a minimum of four iterations.
(b) Did the method exhibit convergence onto its real root? Sketch the plot with the results for each iteration shown.
