Let be a function from the set A to the set B. Let S be a subset of B. We
define the inverse Image of S to be the subset of A whose elements are
precisely all pre-images of all elements of S. We denote the inverse image
of S by f'(S), sof(s)=(ae Alfa) e S). Let be the function from R to
R defined by (x) = x². Find the value of given functions.
