Question
Let X = {n E N :0 <n< 999} be the set of all numbers with three or fewer digits. Define the function f : X → N by f(abc) = a +b+c, where a, b, and c are the digits of the number in X (write numbers less than 100 with leading 0's to make them three digits). In other words, (f) returns the sum of the digits of its input. For example, f(253) = 2+ 5+3 = 10. a. Let A = {n E X : 306 < n < 323}. Find f(A). b. Find ƒ-1({1,3}) c. Find f-'(2). d. Find ƒ '(52).
