The derivative does not exist at integer values of x, but it does exist at all non integer values of x.  If you look at the graph, each of these segments is horizontal, therefore the derivative is 0 at all non-integer values of x.

This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition.
