Correct answer with a clear explanation gets thumbs up.

2. Newton-Raphson algorithm 1. Solve the equation: f(x) = 0 for the function f(x)-z3-2z + 1 using the Newton-Raphson algorithm. Run 3 iterations (i.e., compute x1, z2 and x3)Use xo = 0 for the initial guess. 2. Represent graphically these iterations using the graph of the function f shown below (show the tangent lines and the values of xo, x1 and x2 f(x)-x3-2 x +1 2.5 0 -0.5 -1 -0.5 0.5 . Figure 1 3. Compute the approximate absolute error, Ea, for the last 2 iterations and complete the following table
