`f(x)={x if x` is rational `-x if x` is irrational then `Lt_(x->0) f(x) =`

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

f(x)={1 if x is rational then -1 if x is irrational then Lt_(x rarr1+f(x))=

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 ,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

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

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 ............

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

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