Complex Calculus Question

Consider the function, 

f(x) = √ x − ln(x)


a) Is this function one-to-one?

b) What is the domain and range of f(x)?

c) Restrict the domain of f(x) such that it is one-to-one (if it wasn’t already), and then sketch the function and its inverse (do not try to find the inverse algebraically). What is the domain and range of your f -1 (x)?
