Consider the function f defined for all real x f x x 4 a Find the x values of the two critical points of f Separate your two answers by a comma b Now use the Second Derivative Test to determine the location and types of the extrema at the critical points you found above The left critical point is a The right critical point is a c Finally using an online graphing tool like Desmos produce the graph of f Notice that f has a local maximum at x 0 Choose the best reason why f has a local maximum at x 0 but no critical point at x 0 f is not continuous at x 0 f is not differentiable at x 0 on this problem
