(a) how many functions are there from a set with three elements to a set with six elements? imagine creating a function from a 3-element set s to another set t as a three-step process. step 1 sends the first element of s to an element in t; step 2 sends the second element of s to an element in t; step 3 sends the third element of s to an element in t. by the ---select--- rule, the number of ways to create a function is the ---select--- of the number of ways to perform each of the three steps. so, the answer is . (b) how many functions are there from a set with four elements to a set with two elements? (c) how many functions are there from a set with m elements to a set with n elements, where m and n are positive integers? need help?
