Write the number of points of discontinuity of `f(x)=[x]` in `[3,7]`.

Let g(x)=f(f(x)) where f(x)={1+x;0<=x<=2} and f(x)={3-x;2

Let g(x) = f(f(x)) where f(x) = { 1 + x ; 0 <=x<=2} and f(x) = {3 - x; 2 < x <= 3} then the number of points of discontinuity of g(x) in [0,3] is :

Let f(x)=[3+2cos x],x in(-(pi)/(2),(pi)/(2)) where [.] is the GIF .Then the number of points of discontinuity of f(x) is

Let f (x)= signum (x) and g (x) =x (x ^(2) -10x+21), then the number of points of discontinuity of f [g (x)] is

Let f (x)= signum (x) and g (x) =x (x ^(2) -10x+21), then the number of points of discontinuity of f [g (x)] is

Given f(x)=|x+1| if x =3 then number of points of discontinuity of f(x) is

Number of point of discontinuity of f(x) = (1)/(x - [x]) is

Let f(x)=sin x cos x. Write down the set of points of discontinuity of f(x).
