Let A be the collection of all finite nonempty subsets of N. Define two functions f: N -> A and g: A -> N as follows. Let f(n) = {n}, g(E) = min(E). For example, f(4) = {4}, g({3,5,8}) = 3.
Which of the following statements is correct?
Select one:
a. g is a left inverse for f
b. g is a right inverse for f
c. g is the inverse of f
d. g is neither a left inverse nor a right inverse for f
