• The set A is called the domain of f and the set B is known as its co-domain. The set of images of elements of set A is known as the range of f.
• A function f: A → B is a one-one function or an injection, if f(x) = f(y) ⇒ x = y for all x, y ∈ A or, x ≠ y ⇒ f(x) ≠ f(y) for all x, y ∈ A.
• A function f: A → B is an onto function or a surjection, if range (f) = co-domain (f).

Note: A function which is both one-one and onto function is called a bijective function.
