Answer:
Option C
Explanation:
The graph of the function f (x) = x - [x] for the interval (0, 7) is shown below :
It is obvious from the above graph that the function x - [x] is discontinuous at the points x = 1,2,3,4, 5,6. Therefore no. of points of discontinuity of the given function in ths given interval are 6.
