`f(x) = sgn(x^2 - ax + 1)` has maximum number of points of discontinuity then

Let f(x)=g(x)sgn(x^(3)+6x^(2)+11x+6) where sgn denotes signum function and f(x)=ax^(3)+x^(2)+x+1, then minimum number of points of discontinuity of the function f(x) is

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

If f(x) = sgn(sin^2x-sinx-1) has exactly four points of discontinuity for x in (0, npi), n in N , then

If f (x)= tan ^(-1) (sgn (n ^(2) -lamda x+1)) has exactly one point of discontinuity, then the value of lamda can be:

If f (x)= tan ^(-1) (sgn (n ^(2) -lamda x+1)) has exactly one point of discontinuity, then the value of lamda can be:

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 :

If f(x)=sgn(sin^(2)x-sin x-1) has exactly four points of discontinuity for x in(0,n pi),n in N, then

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

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

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