Question

If f: A→B is a bijective function and if n(A)= 3, then n(B) =

Answer 1

Answer:

n(B)=n(A)=3

Step-by-step explanation:

We are given f is a bijective function.

It means f is one-one as well as onto function.

Therefore every element of B is a image in f.

f is one-one therefore image of every element is different.

⇒ number of elements in B should be equal to number of elements in A

Answer 2

Answer:

It means f is one - one as well as onto function.

Therefore every element of B is a image in f.

F is one - one therefore image of every elements is different.

=> number of elements in B should be equal to the number of electrons in A.

n(B) = n(A) = 5
