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