Question
Find the number of many-one function between two sets $A=(3,4,5\}$ and $B=\{2,3,4,5\}$.
Step 1
The total number of functions from a set with m elements to a set with n elements is given by n^m. Here, m=3 (the number of elements in set A) and n=4 (the number of elements in set B). So, the total number of functions is 4^3 = 64. Show more…
