How many different functions can be defined from a set of 5 elements to a set of 9 elements?


5

9

45

59

95


Yanıt Açıklaması:

Constant functions map every element from their domain to the same element of the range. We may therefore define a constant function for every element in the range. Since there are 9 different elements in the range we may write 9 different constant functions.
