Discontinuity Of A Function

We are given , the greatest integer function. The function is discontinuous at values of where is an integer, say . That occurs at , for all . So there are infinitely many discontinuities in , but we are interested in points where the function is **actually discontinuous**. However, due to the greatest integer function behavior, these discontinuities happen at each such value. Upon re-checking the actual image, the number of discontinuities in is **infinite**, but the marked answer is (2) — which is **incorrect**. The **correct answer** should be: % Correct Answer % Correct Answer Correct Answer:} (4)
