Explanation:
function from S_1 to S_2 (functions have unique mapping
each element in S_1 has 2 elements to map to in S_2 and there are 3 elements in S_1
therefore number of functions = 2^3 = 8 (2 choices for each of 3 elements)
a) relations between S_1 and S_2 are subset of S_1 x S_2
there are 6 elements in S_1 x S_2 therefore relations would be 2^6 = 64
(no of subsets of set of n elements = 2^n)
b) By above explanation functions from S_2 to S_1 = 3^2 = 9
and relation from S_2 to S_2 = 2^4 = 16
