    Finding Critical points on a given graph

    So i cant seem to locate the critical points on this graph. I know critical points are where f'(c)=0 or f(c) is not differentiable. I know X1 is one. But i'm unsure about the rest. Also they didnt give an equation, only the graph.

    Thanks for the help.

    They are only after the places where the derivative is zero. Where would you say those points are?

    I would say x0 and x4 and maybe X2. Which look like relative min to me. X1 is undefined and x3 are other. Does that seem right?
