5. Consider the function f(x). f(x) = (2x² + 3x + 1 |x| sin(x - 1) + 1 if x < -1 if -1 < x < 1 if 1 < x -1, (a) Check if f(x) has a derivative at x = -1. If f(x) has a derivative at x = - then give the derivative. If not, explain why. (b) Check if f(x) has a derivative at x = 1. If yes, then give the derivative of f(x) at x = 1. If not, explain why.
