Question:
The set of points of discontinuity of f(x) = [x] is ___________.
Solution:
The graph of f(x) = [x] is shown below.
It can be seen that, the function f(x) = [x] is discontinuous at all integral values of x i.e. x ∈ Z.
Thus, the set of points of discontinuity of f(x) = [x] is the set of integers i.e. Z.
The set of points of discontinuity of f(x) = [x] is __the set of integers i.e. Z___.
