Use the graph of g in the figure to do the following. a. In the interval ( - 2,4), g is not continuous at x = a. Find the values of x in ( - 2,4) at which g is not continuous. (Use a comma to separate answers as needed.) b. Find the values of x in ( - 2,4) at which g is not differentiable. b. In the interval ( - 2,4), g is not differentiable at x = (Use a comma to separate answers as needed.) X b 5
