For two sets and , a function
exists from to . Also, ,
, and means is a
multiple of . If ,
, and , find the range of the function.
To say is multiple of , it means that , where is an integer.
Test the elements in to find the range of .
4 is a multiple of 2 because , then maps 4 to 2, so 2 is in the range.
15 is a multiple of 3 because , then maps 15 to 3, so 3 is in the range.
