Top 4 Videos on Functions for CAT Quantitative Aptitude by PW

Functions is an important topic to understand while preparing for CAT Quantitative Aptitude, but solving its questions can be challenging. You may understand the basic definition of a function yet struggle with composite functions, modulus expressions, or special function patterns. Choosing the right method and solving questions accurately can become even more difficult when you are revising several concepts together.

These top 4 videos on Functions for CAT Quantitative Aptitude by MBA Wallah cover these topics through concept explanations, worked examples, quick solving methods, and previous-year questions. You can choose a lesson based on your preparation needs, whether you want to learn the basics, practise modulus questions, understand special functions, or revise the chapter before attempting CAT-level problems.

Video 1: Master Modulus Functions with One-Shot Concepts and CAT PYQs

This one-shot video covers Modulus Functions through concept explanations and exam-style questions. You will learn about the meaning of modulus, linear modulus expressions, comparisons between modulus expressions, nested modulus, and questions involving multiple modulus terms.

The lesson also covers graph-based questions, maximum and minimum values, and aptitude applications. CAT and XAT previous-year questions are followed by a higher-level practice segment, allowing you to apply the concepts to different problems.

If modulus questions are difficult for you, this video can help you revise the key ideas and practise the methods used to solve them.

Video 2: Learn Functions and Composite Methods with Quick Modulus Practice

This video introduces the meaning of Functions before moving to composite functions and modulus. You will learn the basic idea of a function, understand composite functions, and explore shorter methods for solving related questions.

The modulus section covers key concepts, solving methods, and quick approaches, along with CAT previous-year questions. If you are starting this topic or need to revise its fundamentals, the video helps you connect basic definitions with their applications.

You can use the explanations to recall the concepts, practise choosing suitable methods, and prepare for questions that combine Functions, composite operations, and modulus.

Video 3: Revise Functions in One Shot with Five Years of CAT PYQs

This one-shot video brings together the fundamentals of Functions, composite functions, and different types of special functions. After explaining the concepts and useful solving approaches, the lesson moves to CAT-level questions and previous-year questions from five past exam cycles.

You can use this video to revise several parts of Functions in one sitting and understand how the concepts are applied to exam questions.

If you have already studied the basics, watching the lesson before a mock test or sectional practice can help you revisit important ideas, work through different question types, and identify the areas that need further practice.

Video 4: Build Composite Function Clarity with Step-by-Step Questions

This video begins with the meaning and fundamentals of Functions before moving to practice questions and important problem types. It then introduces composite functions and explains their main concepts through dedicated questions.

The lesson progresses from the introduction to concept learning, problem-solving and a closing review. If you find it difficult to move from understanding a definition to applying it in a question, you can follow the explanations and practise each concept in sequence.

Use this video when learning Functions for the first time or revising the basics before attempting composite-function questions independently.

Preparing Functions for CAT Quantitative Aptitude requires you to understand the concepts and apply them to different types of questions. These four PW videos cover the basics of Functions, composite functions, modulus expressions, special functions, and previous-year questions.

You can begin with the concept lessons if you need to strengthen your understanding, move to focused videos for modulus and special functions, and use the one-shot lesson to revise key topics with CAT-level questions.

Choose the video that matches your current preparation needs and practise the questions alongside the explanations. This approach can help you revise Functions more effectively and become more familiar with the methods used to solve its different question types.
