Question 2: (20 points) Consider the function signum sgn x = 1, -1, x > 0, x = 0, x < 0. Find the general global solution of the differential equation y" + (sgn x) y = 0. N.B. The general global solution is a function y: RR that is twice differentiable and verifies the differential equation (1) on R.
