If `f(x)={:{ (x-2 ,x <= 0), (4-x^(2),x>0) :}` ,then number of points, where `y=f(f(x))` is discontinuous is

The number of points where f(x) is discontinuous in [0,2] where f(x)={[cos pi x]:x 1}

Let f(x)=abs(2x^2+5abs(x)-3) If m is the number of points where f(x) is discontinuous and m is the number of points where f(x) is non-differentiable then value of m+n is

" The function "f(x)=(1)/(x-(x))" .The number of points at which "f(x)" is discontinuous is "

If y=(1)/(t^(2)+t-2), where t=(1)/(x-1), then find the number of points where f(x) is discontinuous.

If f (x)= [{:(x,,, "if x is rational"), (1-x,,," if x is irrational "):}, then number of points for x in R, where y =f (f (x)) discontinous is:

If f(x)=||x|-1| ,then the number of points where f(x) is not differentiable is

Let f(x)=max*{|x^(2)-2|x||,|x|} then number of points where f(x) is non derivable, is :
