RELATIONS & FUNCTIONS Exercise 1.3 | Q6 | Class 12 NCERT Solutions | Prove a function invertible? - Videos

In this video, we will discuss an important concept which is the definition of an invertible function in detail. We will also learn how to prove or identify whether a given is invertible and find its inverse.
f:X→Y is called INVERTIBLE, if there exists a function g:Y→X such that:
gof=I_x and fog=I_y
f^(-1)=g and g^(-1)=f
