In this video, we study the chapter Inverse of Functions and solve Exercise 1.2 – Question No. 2 and Question No. 3 in detail.
📗 Question No. 2
For the given real valued functions, we:

Find f⁻¹(−1)
And verify:
. 𝑓(𝑓−1(𝑥))=𝑥
. 𝑓−1(𝑓(𝑥))=𝑥
All parts are explained step by step using simple methods.
📗 Question No. 3
Without finding the inverse function, we:
State the domain of f⁻¹
State the range of f⁻¹
Use the relationship between domain and range of a function and its inverse
This video is very useful for Class 12 / 2nd Year Mathematics students, especially for board exam preparation.
