Question

If f:A to B is a bijection function and if n(B)=7 than n(A) is equal to​

Answer 1

Answer:

n(A)= 7

Step-by-step explanation:

Bijective Function :

If the function 'f' is both one-one

and onto then it is called a bijective

function .

If f : A - > B is a bijective Function

then n( A ) = n( B )

Hope it helps.

Answer 2

In a bijective function, n(A) = n(B)  ⇒ n(A) = 7
