Question

# If f(x) is a real valued function discontinuous at all integral points lying in [0,n] and if then number of functions f(x) are

## The correct answer is:

### There are four possible functions defined in of them 2 are continues and two are discontinuous now for each of the points (1,2,, n-1), keep functions fixed from left of the point so there are 4 possible functions defined in between next two consecutive integral points of them only is continuous and at last for x=n there is only one possibility of discontinuity of the function. So total number of functions=
