NCERT Class 12 Maths Relations and Functions Exercise 1.2 comprises important points that students must remember if they want to do well in their exams. Students can refer to these important points from exercises 1.2 types of functions below:

- Let A and B be two non-empty sets. Then, a function f from A to B associates every element of A to a unique element of B.
- 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.
