`f` is defined in `[-5, 5]` as `f(x) = x` if x is rational `=-x` if x is irrational. Then

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

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

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^(2) if x is rational and 0, if x is irrational }, then

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

If f(x) is defined on [0, 1] by the rule f(x)={x, if x is rational , 1-x, if x is rational ' then for all x in [0,1] , f(f(x)) is

If f(x) is defined on [0,1] by the rule f(x)={x, if x is rational 1-x, if x is rational ' then for all x in[0,1],f(f(x)) is

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

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