Question
Let 
be a function defined by f(x) = log(logx)) the base of the logarithm being e. Then
- f is one one and onto
- f is one one but not onto
- f is onto but not one one
- The range of f is equal to its domain
The correct answer is: f is one one and onto
F (x) = log (log (log x))
In
, f(x) > 0 
strictly increasing
onto
