The inverse of a function f is a function f^ (-1) such that, for all x in the domain of f, f^ (-1) (f (x)) = x. Similarly, for all y in the domain of f^ (-1), f (f^ (-1) (y)) = y. Can you always find the inverse of a function? Not every function has an inverse. A function can only have an inverse if it is one-to-one so that no two elements in ...QuickMath will automatically answer the most common problems in algebra, equations and calculus faced by high-school and college students.
