Let f(x) be given that `f(x)={{:(,x,"if x is rational"),(,1-x,"if x is irrational"):}`
The number of points at which f(x) is continuous, is

If f(x)={(x",", "if x is rational "),(-x",","if x is irrational"):} , then

If f(x)={{:(1,"x is rational"),(2,"x is irrational"):} then

Let f(x) = [{:(x^(2), " if x is irrational"),(1, " if x is rational"):} , then

Let f defined on [-5, 5] as f(x)={{:("x, if x is rational"),("-x, if x is irrational"):}, then f(x) is

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:

f is defined on [-5,5] as f(x)= {{:("x if x is rational"),("-x if x is irrational"):}

Let f (x)= {{:(sin ^(2) x"," , "x is rational"),(-sin ^(2)x",", " x is irrational"):}, then set of points, where f (x) is continuous, is:

If f(x)={x, when x is rational,1-x, when x is irrational,then
