Question

if A = {1 2 3} and B={4 5 6 7}. find the total number of possible function from A to B.

Answer 1

Answer:

total number of functions from A to B = 4096.

Step-by-step explanation:

Total number of elements in A×B = n(A)×n(B) = 3×4 = 12

So, total number of functions from A to B = total number of subsets of A×B = 2^12 = 4096.
