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

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

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

f(x)={x if x is rational -x if x is irrational then Lt_(x rarr0)f(x)=

If f(x)={x^(2) if x is rational and 0, if x is irrational }, then

Let f(x)={x^(n),x is rational and -x^(n),x is irrational then f(x) is discontinuous at x=0 if n

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

Discuss the continuity of f(x)={x^2, x is rational -x^2, x is irrational dot

If f:[0,1] rarr [0,1] be difined by f(x) = {(x," if x is rational"),(1-x," if x is irrational"):} then fof(x) is ............

If f:[0,1]to[0,1] is defined by f(x)={{:(x," if x is rational"),(1-x," if x is irrational"):} , then (fof)(x) is
