In this video, we will discuss two methods (Method for CBSE & Method for IIT JEE – Graphical Method), how we can identity whether a function is a ONE-ONE function and ONTO function.

Class 12 NCERT Exercise 1.2 Questions 6 is discussed in this video.
In each of the following cases, state whether the function is one-one, onto or bijective. Justify.
(i) f:R→R given by f(x)=3-4x (ii) f:R→R given by f(x)=1+x^2
