PSEB Class 12 Relations and Functions Practice

Relations and Functions is an important part of Class 12 Mathematics. This practice test is designed to help students review the basic properties of relations and the main types of functions through short multiple-choice questions. The test contains 20 questions with four answer options, instant result checking, and explanations that can be used for independent revision.

The topic requires more than memorizing definitions. Students should be able to examine a relation and decide whether it is reflexive, symmetric, or transitive. They should also understand when a relation is an equivalence relation and how the properties of a function affect whether it is one-to-one, onto, or invertible.

Use this test as a quick revision activity before broader Mathematics practice. After completing all questions, review every explanation carefully, especially when an answer was selected by guessing. Repeat the test after revising weak concepts.

What to Review for Relations and Functions

Focus on definitions, mathematical properties, and the differences between common types of relations and functions.

Types of Relations

Review reflexive, symmetric, and transitive relations. Practice checking each property separately and deciding whether a relation satisfies the conditions required for an equivalence relation.

One-to-One and Onto Functions

Practice identifying one-to-one functions and onto functions. Review how inputs are connected with outputs and how the domain, codomain, and range can affect the classification of a function.

Composition and Invertible Functions

Review composition of functions, the order of composition, and invertible functions. Practice determining when an inverse exists and how function properties are connected with invertibility.

Key Relations and Functions Concepts

Before repeating the test, make sure you can explain the meaning of each important term without relying only on a memorized example. A strong understanding of definitions makes it easier to solve questions where a relation or function is presented in an unfamiliar form.

  • Relation on a set
  • Reflexive relation
  • Symmetric relation
  • Transitive relation
  • Equivalence relation
  • Function, domain, codomain, and range
  • One-to-one function
  • Onto function
  • Composition of functions
  • Invertible function

Common Mistakes to Check

Relations and Functions questions often look simple, but a small mistake in a definition can lead to the wrong answer. When reviewing your result, check whether you made one of these common errors:

  • Checking only one ordered pair when testing a relation property
  • Confusing symmetric and transitive relations
  • Calling a relation an equivalence relation without checking all required properties
  • Confusing the range of a function with its codomain
  • Mixing up one-to-one and onto functions
  • Changing the order when composing two functions
  • Assuming that every function has an inverse
  • Using examples instead of applying the exact mathematical definition
