1. Given a function f, its inverse function (if it exists) is the function f-1 such that y = f(r) if and only if f-1(y) = x. (a) If we know that f()) = , what is f-1()? What about f(f-1())? (b) If we know a function has an inverse function, what do we know about the properties, behavior, or appearance of its inverse function? Create a list of these attributes
