Function discontinuous at all integers and continuous everywhere
Not what you're looking for?
My teacher gave the class a few examples of functions that are continuous at all integers and discontinuous everywhere else. He then asked us if it is possible to have a function that is discontinuous at all integers and continuous everywhere else. He informed us that there is and that we should try finding it and a graph to show it's a function for mathematics practice.
