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

The function f(x)={[(|x|)/(x) , if x!=0],[0, if x=0 is discontinuous at

If f(x)={[x^(3)+3:x!=0, is discontinuous at

If f(x)={sin((1)/(x)),x!=00,x=0 then it is discontinuous at-

Prove that f(x) = x^(3)+3 if x!=0 and 1 if x=0 is not differentiable at x = 0.

Show that f(x)={1+x^(2),quad if quad 0 is discontinuous at x=1

If f(x)={xe^-(1/|x|+1/x) , x!=0 ,, 0, x=0 (1) discontinuous everywhere(2) continuous as well as differentiable for all x(3) continuous for all x but not differentiable at x=0(4) neither differentiable nor continuous at x = 0

Show that the function f(x) given by f(x)={(e^(1/x)-1)/(e^(1/x)+1), when x!=00,quad when x=0 is discontinuous at x=0

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

Show that f(x)={1+x^(2), if 0 1 is discontinuous at x=1

Function f(x)=x-|x| is discontinuous at x=0
