If `f(x)=(1+x)/([x]),x in[1,3]`, then the number of points of discontinuity are (where `[.]` is G.I.F.)

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

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

Given f(x)=1/(x+2) , write down the set of points of discontinuity of f (f(x)).

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

The number of points of discontinuity of g(x)=f(f(x)) where f(x) is defined as,f(x)={[1+x,0 2

If f(x) = sgn (x) and g (x) = (1-x^2) ,then the number of points of discontinuity of function f (g (x)) is -

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

If f(x)=(1)/(x-1) and g(x)=(x-2)/(x+3), then number of points of discontinuity in f(g(x))is(1)1(2)2(3)3(4)4

If f(x) = [[x^(3),|x| =1] , then number of points where f(x) is non-differentiable is
