This lesson explores the classification of functions in mathematics for CBSE Class 11 (aligned with the NCERT textbook). You will learn to define different classes of functions - one-to-one (injective), onto (surjective), bijective, into, and many-to-one - along with their mathematical properties and representations using Venn diagrams. The lesson also covers how these functions are applied in various mathematical contexts and their significance in problem-solving.
