Consider a function f : S→T defined by f(n) = n², where the domain is the set of consecutive integers S = {-7,..., -2, -1, 0, 1, 2, ..., 7} and the range is the set of consecutive squares T = {-64,..., -9,–4, −1, 0, 1, 4, 9, . . . ,64}. Which one of the following choices correct describes f? Oone-to-one, but NOT onto Oonto, but NOT one-to-one O one-to-one and onto Oneither one-to-one nor onto Onone of these
