Question 2. We say that a function f is invertible if f--{(ba) : (a, b) function, in which case we call it the inverse function to f. Notice that f} is also a f- (b) = a-> b = f (a) (assuming that f-1 is a function). We define the range of a function f DR to be the set {f(x): r E D], i.e., the set of...
