2 - Determining Differentiability Graphically LEARNING OBJECTIVE: Decide the value(s) of * for which ((x) is not differentiable by using graphical properties. For the graph shown below, find all values of x for which f(x) is not differentiable. 6 5 3 2 1 -6 -5 -4 -3 -1 2 3 5 6 -2 -3 4 -5a.) 7(x) is differentiable for all x-values. ( b.) x =0, x = 1, x = 2 ( ) x= 1, x = 2 ( d.) x = 2
