Domain and Range of a function

Welcome to this lesson on Domain and range of a function. This is a part of Relations and Functions/Class 11 Maths. Understanding Domain and Range of a function plays an important role in Inverse Trigonometric functions and in Calculus.

Here, you will learn about functions, their domain, codomain and range. A number of problems are explained . The interesting fact about algebraic functions-domain and range is that each problem follows a different approach. As I tell my students, you have to practice each problem to understand it better.

Is this concept clear? You can mail me your queries at
