y = | x2 - 3x + 1 | y = x - 1 For this case what we must do is solve the system of equations. Applying the graphic solution we have the following solutions: x = 2, y = 1 x = 2 + root (2), y = 1 + root (2) Note: see attached image for the solution. Rewriting the solutions we have: x = 2, y = 1 x = 3.4, y = 2.4 Answer: The approximate solutions are: (2, 1) (3.4, 2.3)
