If f(x)=sgn(x^(3)-x) is discontinuous at x

f(x)=[(x^(3)+4x)/(2)] is discontinuous at x equal to (where [.] denotes the greatest integer function)

The function f(x)=(1)/(x^(2)-3|x|+2) is discontinuous at the points

The function f(x) = (|3x-4|)/(3x-4) is discontinuous at

Find the number of points where f(x)=[(x)/(3)],x in[0,30], is discontinuous (where I.Jrepresents greatest integer function).

The function f(x)=sin^(-1)(cos x) is discontinuous at x=0 continuous at x=0 differentiable at x=0 non of these

The function f(x)=sin^(-1)(cos x) is discontinuous at x=0 (b) continuous at x=0( c) differentiable at x=0 (d) none of these

2.If f(x)={[x^(3)+3:x!=0, and 1 : x=0 " is discontinuous at : -

Statement I f(x) = sin x + [x] is discontinuous at x = 0. Statement II If g(x) is continuous and f(x) is discontinuous, then g(x) + f(x) will necessarily be discontinuous at x = a.
