In this video, we solve Exercise 3.1 Question 3 (Part 1) from the Class 11 Math New Book 2025 (Punjab, KPK, Sindh, Federal Boards). We cover the inverse of quadratic functions, their domain & range, and step-by-step problem-solving techniques as per the atest syllabus 2025.  
🔹 Struggling with inverse functions? This tutorial breaks it down in the easiest way possible!  
🎯 Key Topics Covered:

✔ Quadratic Functions Review (Definition, Graph, Vertex Form)  

✔ Inverse Functions Explained (Algebraic Method + Graphical Understanding)  

✔ Domain & Range Restrictions (How to Identify Valid Inputs/Outputs)  

✔ New Syllabus 2025 Updates (Changes from Previous Editions)  

✔ Exam-Tips & Shortcuts (Save Time in Board Exams!)  
📢 Frequently Asked Questions (FAQs): 
❓ What is the inverse of a quadratic function?

The inverse reverses the input-output relation. For f(x) = ax² + bx + c, we swap x and y and solve for y.  
❓ How to find domain & range of inverse functions?  

- Domain of Inverse= Range of Original Function  

- Range of Inverse = Domain of Original Function  

(Example solved in video!)

❓ Is the inverse of a quadratic function always a function?

No! Only if the original function is one-to-one (restricted domain).  
❓ What’s new in Class 11 Math Book 2025?

Updated exercises, revised syllabus, and more application-based questions.
